Message-ID: <20090123210348.GF30486@tuxdriver.com> (raw)
Dave,
Another quick round of fixes intended for 2.6.29...
The p54 and rtl8187 fixes are simple changes inspired by other fixes
already in 2.6.29. The iwlwifi one fixes an annoying WARN_ON that
people are hitting quite a bit.
Please let me know if there are problems! A batch for net-next-2.6 is
coming soon!
John
