code cleanup. @B83C: I guess the ams520kt01 can use this aswell. Whats left? Actually one brightness cmd takes up to 400ms and when juggling a brightness slider I occasional get:
but that did not hurt so far. @B83C: I'd like some enlightenment on the Temp1? / Temp2? cmds ... do we need them?! |

[ Upstream commit 205c503 ] With lockdep enabled, calls to the connect function from cfg802.11 layer lead to the following warning: ============================= WARNING: suspicious RCU usage 6.7.0-rc1-wt+ msm8916-mainline#333 Not tainted ----------------------------- drivers/net/wireless/microchip/wilc1000/hif.c:386 suspicious rcu_dereference_check() usage!

Fix RCU dereference usage by moving it to a RCU read critical section.
