Subject: pull request: wireless-2.6 2011-04-11
Dave,
Here is another batch intended for 2.6.39. Included is an mwl8k fix
to avoid freeing an irq that we never requested, an ath common code
fix to add a regulatory domain mapping code, an ath9k fix to avoid some
crashes on MIPS boards and fix some radio stability issues on AR9285, a
p54 fix to avoid a device lock-up caused by an uninitialized variable,
an iwlagn fix to correct for an incorrect antenna configuration value
in EEPROM on iwl5300 hardware, and an Kconfig fix for iwlegacy to
keep old kernel build configurations still building iwl3945 and/or
iwl4965 after the iwlagn/iwlegacy split.
Please let me know if there are problems!
John
