-Subject: [PATCH] From 3a32be40f78404d5f1185f0b3d6b5632381cb33f Mon Sep 17 00:00:00 2001
- Subject: [PATCH] [neo1973 leds] Move from mutex to spinlock because we may not use mutexes
- The led triggers may call set_brightness from atomic contexts. As
- mutex_lock calls might_sleep and sleeping is not allowed in atomic contexts
- we have to switch to spinlocks here.
