[PATCH v2 4/8] ath6kl: Move WOW patterns config code to a separate function.

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

 



From: Raja Mani <rmani@xxxxxxxxxxxxxxxx>

Move the user provided WOW patterns configuration code
from ath6kl_wow_suspend() to a separate function called
ath6kl_add_usr_wow_patterns().

It gives more modularity to the existing code.
