From: Christian Lamparter Date: Sat, 18 Oct 2008 21:18:01 +0000 (+0200) Subject: p54: more definitions form lmac_longbow.h and pda.h X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9e7f3f8e4acdc480584d6b5e6a6be5d1f7bda8fa;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git p54: more definitions form lmac_longbow.h and pda.h This patch ports more useful features to p54 - PDR definitions for the synth chips & regulatory domain. - honour IEEE80211_TX_CTL_ASSIGN_SEQ flag, if it's set. - adds some lost mutex_lock & mutex_unlock. - replace two more "magic values" that sneaked past.
