From: Felix Fietkau Date: Sat, 14 Dec 2013 17:03:39 +0000 (+0100) Subject: ath9k_hw: remove defunct ad-hoc mode ATIM window handling code X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=60c4bf29747ebcc2c467c1143a512cee92fc673f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ath9k_hw: remove defunct ad-hoc mode ATIM window handling code The hardware does not have support for ATIM processing, and the driver does not set up ah->atim_window anywhere. Additionally, the code can clobber the timer used by P2P powersave. Signed-off-by: Felix Fietkau Signed-off-by: John W.
