X-Git-Tag: upstream/snapshot3+hdmi~6997^2~57^2~287^2~157

ath6kl: Remove useless initialization in ath6kl_read_fwlogs()

ath6kl_read_fwlogs() assigns the value zero to the variable 'ret'
at the time of declaration. Later, return value of ath6kl_diag_read32()
repalces the init value. Hence removing useless zero assignment.
