USB: rtl8187: remove __devinit* from the struct usb_device_id table

2012-09-14T17:00:21+00:00

commit a3433179d0822ccfa8e80aa4d1d52843bd2dcc63 upstream.

This structure needs to always stick around, even if CONFIG_HOTPLUG
is disabled, otherwise we can oops when trying to probe a device that
was added after the structure is thrown away.

Thanks to Fengguang Wu and Bjørn Mork for tracking this issue down.

rtl8187: ->brightness_set can not sleep

2012-07-16T16:04:42+00:00

commit 0fde0a8cfd0ede7f310d6a681c8e5a7cb3e32406 upstream.

Fix:

BUG: sleeping function called from invalid context at kernel/workqueue.c:2547
in_atomic(): 1, irqs_disabled(): 0, pid: 629, name: wpa_supplicant
2 locks held by wpa_supplicant/629:

 #1:  (&trigger->leddev_list_lock){.+.?..}, at: [] led_trigger_event+0x21/0x80
Pid: 629, comm: wpa_supplicant Not tainted 3.3.0-0.rc3.git5.1.fc17.i686
Call Trace:

Removing _sync is ok, because if led_on work is currently running
it will be finished before led_off work start to perform, since
they are always queued on the same mac80211 local->workqueue.

USB: convert drivers/net/* to use module_usb_driver()

2011-11-18T17:44:20+00:00

This converts the drivers in drivers/net/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

drivers/net: Add module.h to drivers who were implicitly using it

2011-10-31T23:31:07+00:00

The device.h header was including module.h, making it present for
most of these drivers.  But we want to clean that up.  Call out the
include of module.h in the modular network drivers.

mac80211: pass vif param to conf_tx() callback

tx params should be configured per interface.
add ieee80211_vif param to the conf_tx callback,
and change all the drivers that use this callback.

The following spatch was used:

TSF can be kept per vif.

rtl8187: Change rate-control feedback

2011-03-04T19:05:17+00:00

The driver for the RTL8187L chips returns IEEE80211_TX_STAT_ACK for all
packets, even if the maximum number of retries was exhausted. In addition
it fails to setup max_rates in the ieee80211_hw struct, This behavior
may be responsible for the problems noted in Bug 14168. As the bug is very
old, testers have not been found, and I do not have the case where the
indicated signal is less than -70 dBm.

mac80211: make tx() operation return void

2011-02-25T20:32:34+00:00

The return value of the tx operation is commonly
misused by drivers, leading to errors. All drivers
will drop frames if they fail to TX the frame, and
they must also properly manage the queues (if they
didn't, mac80211 would already warn).

Removing the ability for drivers to return a BUSY
value also allows significant cleanups of the TX
TX handling code in mac80211.

Note that this also fixes a bug in ath9k_htc, the
old "return -1" there was wrong.
