mtd: change struct flchip_shared spinlock locking into mutex
commit 8ae664184c45def51ff0b61d4bd6c6671db6cb4f upstream.
This patch prevent to schedule while atomic by changing the
flchip_shared spinlock into a mutex. This should be save since no atomic
path will use this lock.
It was suggested by Arnd Bergmann and Vasiliy Kulikov.
