Merge git://git.infradead.org/~dwmw2/firmware-2.6
* git://git.infradead.org/~dwmw2/firmware-2.6:
qla1280: Fix off-by-some error in firmware loading.
Add README.AddingFirmware file. Basically telling people not to.
firmware: Remove newly-added slicoss and sxg firmware images
firmware/WHENCE: Add missing origin information for Ambassador atmsar11.fw
ALSA: wavefront - Always use request_firmware()
Remove fdump tool for av7110 firmware
firmware: convert av7110 driver to request_firmware()
Partially revert "V4L/DVB (9533): cx88: Add support for TurboSight TBS8910 DVB-S PCI card"
Revert "fix modules_install via NFS"
Add-add conflicts in firmware/WHENCE fixed manually
