From: Johannes Berg Date: Fri, 9 Mar 2012 07:58:46 +0000 (+0100) Subject: iwlwifi: remove no_sleep_autoadjust X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=84965795b2908f2e0be929e71b5bf3b7c6ad5329;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git iwlwifi: remove no_sleep_autoadjust My original idea with this was to adjust the sleep pattern of the uCode based on the maximum network latency userspace asked for. Due to nobody wanting to test it, this logic was disabled by default. It seems the time has come to remove it, since it's not only always disabled but there also don't seem to be any applications that actually request a max network latency.
