2013-09-17usb: gadget: fix a bug and a WARN_ON in dummy-hcdAlan Stern1-3/+4
This patch fixes a NULL pointer dereference and a WARN_ON in dummy-hcd. These things were the result of moving to the UDC core framework, and possibly of changes to that framework. Now unloading a gadget driver causes the UDC to be stopped after the gadget driver is unbound, not before. Therefore the "driver" argument to dummy_udc_stop() can be NULL, so we must not try to print the driver's name without checking first. Also, the UDC framework automatically unregisters the gadget when the UDC is deleted. Therefore a sysfs attribute file attached to the gadget must be removed before the UDC is deleted, not after.

Enable only those interrupts that we can handle & acknowledge in the interrupt handler. At least on EdgeRouter Lite, the hardware may occasionally interrupt with some error condition when the physical link status changes frequently. Since the interrupt condition is not acked properly, this leads to the following warning and the IRQ gets disabled completely: [ 41.324700] eth0: Link down [ 44.324721] eth0: 1000 Mbps Full duplex, port 0, queue 0 [ 44.885590] irq 117: nobody cared (try booting with the "irqpoll" option) [ 44.892397] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.11.0-rc5-edge-los.git-27d042f-dirty-00950-gaa42f2d-dirty #8 [ 44.902825] Stack : ffffffff815c0000 0000000000000004 0000000000000003 0000000000000000 ffffffff81fd0000 ffffffff815c0000 0000000000000004 ffffffff8118530c ffffffff815c0000 ffffffff811858d8 0000000000000000 0000000000000000 ffffffff81fd0000 ffffffff81fc0000 ffffffff8152f3a0 ffffffff815b7bf7 ffffffff81fc6688 ffffffff815b8060 0000000000000000 0000000000000000 0000000000000000 ffffffff815346c8 ffffffff815346b0 ffffffff814a6a18 ffffffff8158b848 ffffffff81145614 ffffffff81593800 ffffffff81187174 ffffffff815b7d00 ffffffff8158b760 0000000000000000 ffffffff814a9184 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 ffffffff811203b8 0000000000000000 0000000000000000 ...

2013-09-17ARM: imx51.dtsi: fix PATA device clockArnaud Patard (Rtp)1-1/+1
Commit 718a350 (ARM: i.MX51: Add PATA support) adds pata support to the imx51.dtsi file and is using clock 161. The problem is that the right clock is 172, according to commit 5d530bb (ARM: i.MX5: Add PATA and SRTC clocks). Using the clock 172 makes things work again (and kills a nasty system freeze).
