This patch fixes the 'scheduling while atomic' errors introduced by
commit 12dac0756d357325b107fe6ec24921ec38661839 ("tg3: adapt tg3 to
use reworked PCI PM code").The first hunk of the patch removes an unnecessary
tg3_set_power_state() call. The chip will already be in the D0 state
either due to a chip reset or through a previous call to
tg3_set_power_state().The second hunk of the patch moves the tg3_set_power_state() call
outside the critical section guarded by tg3_full_lock() and
tg3_full_unlock() functions. The power state of the device is and
should be outside the lock's domain and all other
tg3_set_power_state() calls support this.Signed-off-by: Matt Carlson

Experience with the rtl8187 driver has shown that mac80211 can make
calls to the config callback routine in rapid succession. This patch
creates a mutex that protects the private data in several of the routines
called by mac80211.Signed-off-by: Larry Finger

In the legacy rt2570 driver the link tuner was never
really called. And now the reason has finally become
apparent: It breaks TX capabilitiesAs soon as the device has been associated all following
TX frames will be queued in the hardware and never transmitted
to the air. Disabling sections of the link tuner did not
have the expected result, but completely disabling the
link tuner did have the right result (Both of my rt2570 devices
came back to life).This should fix Fedora bug: 411481

Having the buffer on the stack and even re-using it for all led devices is bad.
Not being able to resolve the name member of the led device structure to a
meaningful value leads to confusion during ad-hoc debugging and potential
breakage in the future, if we ever decide to access the name member outside of
the registration function. Move the buffer to our private per led device
structures so that it is accessible after registration.A quick grep didn't yield any occurence of using the led device name parameter
outside of the led device registration function, so currently we should already
be safe for normal operation.Signed-off-by: Sven Wegener

Currently function tty_ldisc_get() tries to load an ldisc driver module
only when tty_ldisc_try_get() returns -EAGAIN. This happens only if
module is being unloaded. If ldisc module is not loaded
tty_ldisc_try_get() returns -EINVAL and this case is not handled in
tty_ldisc_get(), so request_module() is not called.Attached patch fixes this by calling request_module() if
tty_ldisc_try_get() returned any error code.I discovered this when my UMTS modem stopped working with 2.6.27-rc1
because module ppp_async was not loaded.Signed-off-by: Eugeniy Meshcheryakov

* 'zero-len' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/misc-2.6:
drivers/media, include/media: delete zero-length files -
Each resource should be printed on its own line, so start snprintf'ing
at the beginning of the buffer every time through the loop.Also, use scnprintf() rather than snprintf() when building up the
buffer to print. scnprintf() returns the number of characters actually
written into the buffer (not including the trailing NULL).snprintf() returns the number of characters that *would be* written,
assuming everything would fit in the buffer. That's nice if we want to
resize the buffer to make sure everything fits, but in this case, I
just want to keep from overflowing the buffer, and it's OK if the
output is truncated.Using snprintf() meant that my "len" could grow to be more than the
the buffer size, which makes "sizeof(buf) - len" negative, which causes
this alarming WARN_ON:

Some users of the RTL8187B have experienced difficulties since commit
49292d56352a6ab90d04c3448dd8b6106dfef2d6 that introduced the power
management wext hooks. This difficulty has not made much sense until
it was realized that it was possible for mac80211 to make a call to the
config routine while that routine was already being executed. On this
device, it is necessary to loopback the TX when changing channels. Unless
this is properly restored, the device will lockup. A mutex now protects
the device state, and the private data in several places.The problem was found by Herton Ronaldo Krzesinski ,
who also suggested this type of fix.Signed-off-by: Larry Finger

In kernel version 2.6.26-rc9 my wireless LAN card worked; but in the
released 2.6.26, my RaLink rt2500 card wouldn't associate.Git-bisect led me to this patch:

rt2x00: Remove ieee80211_tx_control argument from write_tx_desc()I believe that there is a problem with that patch --- it
(inadvertantly) removes an extra line of code, that used to set the
DATABYTE_COUNT field.This patch reinstates that line, and with it my card works again.
