[PATCH v2 1/2] ath9k_hw: Fix incorrect macversion and macrev checks

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

 



There are few places where we are checking for macversion and revsions
before RTC is powered ON. However we are reading the macversion and
revisions only after RTC is powered ON and so both macversion and
revisions are actully zero and this leads to incorrect srev checks.

fix this by reading the macversion and revisisons even before we start
using them. There is no reason why should we delay reading this info
until RTC is powered on as this is just a register information.
