From: Helmut Schaa Date: Sun, 11 Jul 2010 10:29:49 +0000 (+0200) Subject: rt2x00: Don't initialize beacon interval to 0 on rt2800 devices X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8544df327c4c1c2bc6f2f6bf2997980d0d9a29f0;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git rt2x00: Don't initialize beacon interval to 0 on rt2800 devices Activating the TBTT interrupt when a beacon interval of 0 is configured results in an interrupt storm causing the machine to hang. Hence, initialize the beacon interval to a reasonable default of 100TUs. Signed-off-by: Helmut Schaa Signed-off-by: Ivo van Doorn Signed-off-by: John W.
