2012-04-11irqdomain: Fix debugfs formattingGrant Likely1-3/+3
This patch fixes the irq_domain_mapping debugfs output to pad pointer values with leading zeros so that pointer values are displayed correctly. Otherwise you get output similar to "0x 5e0000000000000". Also, when the irq_domain is set to 'null' Signed-off-by: Grant Likely <[email protected]> Cc: David Daney <[email protected]> Cc: Mika Westerberg <[email protected]>

2012-04-10irq: Kill pointless irqd_to_hw exportGrant Likely7-31/+11
It makes no sense to export this trivial function. Make it a static inline instead.

2012-04-10irq/irq_domain: Quit ignoring error returns from irq_alloc_desc_from().David Daney1-3/+4
In commit 4bbdd45a (irq_domain/powerpc: eliminate irq_map; use irq_alloc_desc() instead) code was added that ignores error returns from irq_alloc_desc_from() by (silently) casting the return value to unsigned. The negitive value error return now suddenly looks like a valid irq number. Commits cc79ca69 (irq_domain: Move irq_domain code from powerpc to kernel/irq) and 1bc04f2c (irq_domain: Add support for base irq and hwirq in legacy mappings) move this code to its current location in irqdomain.c The result of all of this is a null pointer dereference OOPS if one of the error cases is hit. The fix: Don't cast away the negativeness of the return value and then check for errors.

Commit fe1952fc0afb9a2e4c79f103c08aef5d13db1873 "powerpc: Rework runlatch code" has a nasty typo where it uses "TLF_RUNLATCH" instead of "_TLF_RUNLATCH" (bit number instead of bit mask), causing some flags to be potentially lost such as _TLF_RESTORE_SIGMASK (Brown paper bag for me !

1/ convert open-coded KERN_ERR+dump_stack() to WARN(), so that automated tools pick up this warning. 2/ include the 'child' and 'parent' kobject names. This information was useful for tracking down the case where scsi invoked device_del() on a parent object and subsequently invoked device_add() on a child.

2012-04-10USB: serial: fix race between probe and openJohan Hovold1-0/+8
Fix race between probe and open by making sure that the disconnected flag is not cleared until all ports have been registered. A call to tty_open while probe is running may get a reference to the serial structure in serial_install before its ports have been registered. This may lead to usb_serial_core calling driver open before port is fully initialised.

2012-04-10tcp: fix tcp_rcv_rtt_update() use of an unscaled RTT sampleNeal Cardwell1-2/+5
Fix a code path in tcp_rcv_rtt_update() that was comparing scaled and unscaled RTT samples. The intent in the code was to only use the 'm' measurement if it was a new minimum. However, since 'm' had not yet been shifted left 3 bits but 'new_sample' had, this comparison would nearly always succeed, leading us to erroneously set our receive-side RTT estimate to the 'm' sample when that sample could be nearly 8x too high to use. The overall effect is to often cause the receive-side RTT estimate to be significantly too large (up to 40% too large for brief periods in my tests).

Sounds like a good idea, but that alone doesn't fix anything.

2012-04-10drm/i915: properly compute dp dithering for user-created modesDaniel Vetter1-14/+35
We've only computed whether we need to fall back to 6bpc due to dp link bandwidth constrains in mode_valid, but not mode_fixup. Under various circumstances X likes to create new modes which then lack proper 6bpc flags (if required), resulting in mode_fixup failures and ultimately black screens. Chris Wilson pointed out that we still get things wrong for bpp > 24, but that should be fixed in another patch (and it'll be easier because this patch consolidates the logic). The likely culprit for this regression is commit 3d794f87238f74d80e78a7611c7fbde8a54c85c2 Author: Keith Packard <[email protected]> Date: Wed Jan 25 08:16:25 2012 -0800 drm/i915: Force explicit bpp selection for intel_dp_link_required v2: Fix indentation and tune down the too bold claim that this should fix the world. Both noticed by Chris Wilson. v3: Try to really git add things.

2012-04-10Staging: android: timed_gpio: Fix resource leak in timed_gpio_probe error pathsAxel Lin1-12/+15
If gpio_request fails, we need to free all allocated resources. Current code uses wrong array index to access gpio_data array. So current code actually frees gpio_data[i].gpio by j times. This patch moves the error handling code to err_out and thus improves readability. Signed-off-by: Axel Lin <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2012-04-10staging: iio: ak8975: Remove i2c client data corruptionPreetham Chandru1-3/+5
i2c client data set is of type struct indio_dev pointer and hence the pointer returned from i2c_get_clientdata() should be assigned to an object of type struct indio_dev and not to an object of type struct ak8975_data. Also in ak8975_probe() client data should be set first before calling ak8975_setup() as it references the client data.

I already fixed the other similar for loop in this file. I'm not sure how I missed this one. We use seg_no+1 inside the loop so we can't go right up to the end of the loop. Also if we don't break out of the loop then we end up past the end of the array, but with this fix we end up on the last element.

rtsx_transport.c (rtsx_transfer_sglist_adma_partial): pointer struct scatterlist *sg, which is mapped in dma_map_sg, is used as an iterator in later transfer operation.

2012-04-10staging/media/as102: Don't call release_firmware() on uninitialized variableJesper Juhl1-1/+1
If, in drivers/staging/media/as102/as102_fw.c::as102_fw_upload(), the call cmd_buf = kzalloc(MAX_FW_PKT_SIZE, GFP_KERNEL); should fail and return NULL so that we jump to the 'error:' label, then we'll end up calling 'release_firmware(firmware);' with 'firmware' still uninitialized - not good. The easy fix is to just initialize 'firmware' to NULL when we declare it, since release_firmware() deals gracefully with being passed NULL pointers.

2012-04-10staging: ramster: unbreak my heartDan Magenheimer1-5/+1
The just-merged ramster staging driver was dependent on a cleanup patch in cleancache, so was marked CONFIG_BROKEN until that patch could be merged. That cleancache patch is now merged (and the correct SHA of the cleancache patch is 3167760f83899ccda312b9ad9306ec9e5dda06d4 rather than the one shown in the comment removed in the patch below).
