2012-02-21rt2x00: fix a possible NULL pointer dereferenceGabor Juhos1-1/+2
The 'rt2x00lib_probe_dev' function tries to allocate the workqueue. If the allocation fails, 'rt2x00_lib_remove_dev' is called on the error path. Because 'rt2x00dev->workqueue' is NULL in this case, the 'destroy_workqueue' call will cause a NULL pointer dereference.

2012-02-01rt2800lib: fix wrong -128dBm when signal is stronger than -12dBmLuigi Tarenga1-4/+4
This patch correct the type of variables containing the rssi values read from the rxwi. In function rt2800_agc_to_rssi() 3 variables (rssi0, rssi1, rss2) defined as int was assigned a 16bit signed values as unsigned. From a test with a hi-gain antenna I verified that the rxwi contains signed rssi values in the range -13/+81 (inclusive) with 0 as an error condition. In case of negative values a condition is triggered and the function return -128dBm while the signal is at its maximum. This patch correct the cast so negative values are not treated as very high positive values (ex. -13 does not become 243).

2012-01-13rt2800pci: fix spurious interrupts generationStanislaw Gruszka1-20/+8
Same devices can generate interrupt without properly setting bit in INT_SOURCE_CSR register (spurious interrupt), what will cause IRQ line will be disabled by interrupts controller driver. We discovered that clearing INT_MASK_CSR stops such behaviour. We previously first read that register, and then clear all know interrupt sources bits and do not touch reserved bits. After this patch, we write to all register content (I believe writing to reserved bits on that register will not cause any problems, I tested that on my rt2800pci device). This fix very bad performance problem, practically making device unusable (since worked without interrupts), reported in: https://bugzilla.redhat.com/show_bug.cgi?id=658451 We previously tried to workaround that issue in commit 4ba7d9997869d25bd223dea7536fc1ce9fab3b3b "rt2800pci: handle spurious interrupts", but it was reverted in commit 82e5fc2a34fa9ffea38f00c4066b7e600a0ca5e6 as thing, that will prevent to detect real spurious interrupts.
