staging: vt6655: fix overly large stack usage

2017-05-08T05:44:11+00:00

We get a warning for the large stack usage in some configurations:

drivers/staging/vt6655/device_main.c: In function 'device_ioctl':
drivers/staging/vt6655/device_main.c:2974:1: warning: the frame size of 1304 bytes is larger than 1024 bytes [-Wframe-larger-than=]

This is addressed in linux-3.19 with commit 67013f2c0e58 ("staging: vt6655:
mac80211 conversion add main mac80211 functions"), which obsoletes the
device_ioctl() function, but as that does not apply to stable kernels,
this picks an easier way out by using dynamic allocation.

The driver was merged in 2.6.31, and the fix applies to all versions
before 3.19.

staging: vt6655: device_rx_srv check sk_buff is NULL

2015-07-04T03:02:22+00:00

[ Upstream commit b5eeed8cb6097c8ea660b6598d36fdbb94065a22 ]

There is a small chance that pRD->pRDInfo->skb could go NULL
while the interrupt is processing.

Put NULL check on loop to break out.

vt6655: RFbSetPower fix missing rate RATE_12M

2015-04-17T00:11:44+00:00

[ Upstream commit 40c8790bcb7ac74f3038153cd09310e220c6a1df ]

When the driver sets this rate a power of zero value is set causing
data flow stoppage until another rate is tried.
