Re: [PATCH] ath9k: remove eeprom txgain override for minor version < 19

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'd rather the description included why it needs changing, rather than
just what it does.

I'd add something like:

"This isn't needed for the AR9285; the check originated with the
AR9280 setup code which requires the EEPROM version check."
