2011-02-14zd1211rw: add unlikely to ZD_ASSERTJussi Kivilinna

2011-02-14zd1211rw: move async iowrite16v up to callersJussi Kivilinna
Writing beacon to device happen through multiple write command calls. zd_usb_iowrite16v uses synchronous urb call and with multiple write commands in row causes high CPU usage. Make asynchronous zd_usb_iowrite16v_async available outside zd_usb.c and use where possible. This lower CPU usage from ~10% to ~2% on Intel Atom when running AP-mode with 100 TU beacon interval.

2011-02-14zd1211rw: use async urb for write commandJussi Kivilinna
Writing beacon to device happen through multiple write command calls. zd_usb_iowrite16v uses synchronous urb call and with multiple write commands in row causes high CPU usage. This patch makes zd_usb_iowrite16v use asynchronous urb submit within zd_usb.c. zd_usb_iowrite16v_async_start is used to initiate writing multiple commands to device using zd_usb_iowrite16v_async. Each URB is delayed and submitted to device by next zd_usb_iowrite16v_async call or by call to zd_usb_iowrite16v_async_end. URBs submitted by zd_usb_iowrite16v_async have URB_NO_INTERRUPT set and last URB send by zd_usb_iowrite16v_async_end does not. This lower CPU usage when doing writes that require multiple URBs.

2011-02-14zd1211rw: correct use of usb_bulk_msg on interrupt endpointsJussi Kivilinna
zd1211rw is using usb_bulk_msg() with usb_sndbulkpipe() on interrupt endpoint. However usb_bulk_msg() internally corrects this and makes interrupt URB. It's better to change usb_bulk_msgs in zd1211rw to usb_interrupt_msg for less confusion. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W.

2011-02-14ath9k: disable beaconing before stopping beacon queueRajkumar Manoharan
Beaconing should be disabled before stopping beacon queue. Not doing so could queue up beacons in hw that causes failure to stop Tx DMA, due to pending frames in hw and also unnecessary beacon tasklet schedule.

2011-02-08Bluetooth: ath3k: Avoid duplication of codeRogério Brito
In commit 86e09287e4f8c81831b4d4118a48597565f0d21b, to reduce memory usage, the functions of the ath3k module were rewritten to release the firmware blob after it has been loaded (successfully or not). The resuting code has some redundancy and the compiler can potentially produce better code if we omit a function call that is unconditionally executed in ,---- | if (ath3k_load_firmware(udev, firmware)) { | release_firmware(firmware); | return -EIO; | } | release_firmware(firmware); | | return 0; | } `---- It may also be argued that the rewritten code becomes easier to read, and also to see the code coverage of the snippet in question.
