staging: iio: ade7854-spi: Fix return value

2013-09-18T18:43:33+00:00

ade7854_probe can fail. Return the value obtained from it
instead of 0 (success).

iio: isl29018: Fix uninitialized value

2013-09-18T18:43:25+00:00

The lux_uscale value is not initialized at probe. The value will be
uninitialized unless a value is written to it through the iio channel interface.
This fixes that.

staging:iio:dummy fix kfifo_buf kconfig dependency issue if kfifo modular and buffer enabled for built in dummy driver.

2013-09-18T18:43:23+00:00

This only occurs in the unlikely event that the example driver is built
in whilst the buffer implementation is not.

Solved by switching from a depends on to a select for this particular case.

staging: line6: add bounds check in snd_toneport_source_put()

2013-09-17T14:39:28+00:00

"source" comes from the user in snd_ctl_elem_write() so it needs to be
checked.

Staging: comedi: Fix dependencies for drivers misclassified as PCI

2013-09-17T14:39:28+00:00

The Fastwel UNIOxx-5 is a PC/104 board, so put COMEDI_UNIOXX5 under
COMEDI_ISA_DRIVERS.

The DIL/Net-PC 1486 is a 486 system, so put COMEDI_SSV_DNP under
COMEDI_MISC_DRIVERS and add a dependency on X86_32 || COMPILE_TEST.

staging: r8188eu: Adjust RX gain

2013-09-17T14:39:28+00:00

In some circumstances, the performance of this driver is highly degraded,
and ifconfig reports large numbers of dropped packets. By increasing the
maximum RX gain from 0x3e to 0x4e, performance is greatly improved.

Smatch shows the following warning:
drivers/staging/rtl8188eu/core/rtw_ieee80211.c:161 rtw_set_ie() info: ignoring unreachable code.

The cause is a module exit tracing statement after a return.

  8333                  goto _abort_event_;
  8334          }

This warning results because the number of items in "enum rtw_c2h_event",
which determines the value of MAX_C2HEVT, is one more than in "struct wlanevents".
Adding an extra dummy event to the latter fixes the problem.

staging: r8188eu: Fix Smatch off-by-one warning in hal/rtl8188e_hal_init.c

The reason is that IndexCCK_Base[] has MAX_CHNL_GROUP_24G elements, but
IndexBW40_Base is smaller by 1. Make them both have MAX_CHNL_GROUP_24G
elements.
