Subject: ath6kl: fix compiler warning in ath6kl_init_hw_params()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1b46dc04866a4962644ef32d7398e34b40f7ac21;p=mv-sheeva.git

ath6kl: fix compiler warning in ath6kl_init_hw_params()

Both Luis and John reported that they see a compiler warning:

drivers/net/wireless/ath/ath6kl/init.c: In function 'ath6kl_init_hw_params':
drivers/net/wireless/ath/ath6kl/init.c:1377:26: warning: ‘hw’
may be used uninitialized in this function

Oddly enough I have never seen it. But AFAICT the code is correct and
hw is not used uninitalized so add uninitialized_var() to inform that to
the compiler.
