      [IRDA]: irda-usb bug fixes · 669d32a2
      由 Jean Tourrilhes 提交于 
      This patch fixes 2 bugs in the USB-IrDA code.

The first one is a buffer overrun in the RX path. We are now using
IRDA_SKB_MAX_MTU when initializing the Rx URB.

The second one is a potential stack recursion when unplugging the USB
dongle.  It seems that first we get the Rx URB with a generic error
code, and after a while the Rx URB comes again with a "disconnect"
error code.  Since we are resubmitting the Rx URB immediately after
receiving the first error one, we might enter an endless loop.

When getting an error Rx URB, the patch defers the Rx URB resubmitting
so that it gives us a chance to catch the disconnect one, in case the
dongle has juts been unplugged.

Tested against 2.6.16-rc2.

      [PATCH] wireless/atmel: fix Open System authentication process bugs · 73451379
      由 Dan Williams 提交于 
      This patch fixes a number of bugs in the authentication process:

1) When falling back to Shared Key authentication mode from Open System,
a missing 'return' would cause the auth request to be sent, but would
drop the card into Management Error state.  When falling back, the
driver should also indicate that it is switching to Shared Key mode by
setting exclude_unencrypted.

2) Initial authentication modes were apparently wrong in some cases,
causing the driver to attempt Shared Key authentication mode when in
fact the access point didn't support that mode or even had WEP disabled.
The driver should set the correct initial authentication mode based on
wep_is_on and exclude_unencrypted.

3) Authentication response packets from the access point in Open System
mode were getting ignored because the driver was expecting the sequence
number of a Shared Key mode response.  The patch separates the OS and SK
mode handling to provide the correct behavior.

      [PATCH] wireless/atmel: fix setting TX key only in ENCODEEXT · 0d467502
      由 Dan Williams 提交于 
      The previous patch that added ENCODEEXT and AUTH support to the atmel
driver contained a slight error which would cause just setting the TX
key index to also set the encryption key again.  This patch allows any
combination of setting the TX key index and setting an encryption key.

      [MMC] mmci: allow small data transfers · 0425a142
      由 Russell King 提交于 
      If a data transfer is small (less than a FIFO size) we would
hang waiting for the data to be read due to the PIO interrupt
not occuring.  We allowed for this in our PIO interrupt handler,
but not when setting up a data transfer.

Apply the "fix" when setting up a data transfer as well.

      [PATCH] ide: touch softlockup detector during pio · 651c29a1
      由 Andrew Morton 提交于 
      We're getting some softlockup false positives during heavy PIO operations.  So
poke the lockup detector.

      [PATCH] neofb: avoid resetting display config on unblank (v2) · 9f672004
      由 Christian Trefzer 提交于 
      There were two mistakes in the register-read-on-(un)blank approach.

- First, without proper register (un)locking the value read back will always
  be zero, and this is what I missed entirely until just now.  Due to this,
  the logic could not be verified at all and I tried some bogus checks which
  are completely stupid.

- Second, the LCD status bit will always be set to zero when the backlight
  has been turned off.  Reading the value back during unblank will disable the
  LCD unconditionally, regardless of the state it is supposed to be in, since
  we set it to zero beforehand.

So this is what we do now:

- create a new variable in struct neofb_par, and use that to determine
  whether to read back registers (initialized to true)

- before actually blanking the screen, read back the register to sense any
  possible change made through Fn key combo

- use proper neoUnlock() / neoLock() to actually read something

- every call to neofb_blank() determines if we read back next time: blanking
  disables readback, unblanking (FB_BLANK_UNBLANK) enables it

This should give us a nice and clean state machine.  Has been thoroughly
tested on a Dell Latitude CPiA / NM220 Chip docked to a C/Dock2 with attached
CRT in all possible combinations of LCD/CRT on/off.  I changed the config via
Fn key, let the console blank, unblanked by keypress - works flawlessly.
