[PATCH RT] staging/pohmelfs: convert struct fs->lock usage to seq_spin_{,un}lock

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

This fixes:

	drivers/staging/pohmelfs/path_entry.c:47:2: warning: passing argument 1 of ‘rt_spin_lock’ from incompatible pointer type [enabled by default]
	include/linux/spinlock_rt.h:19:56: note: expected ‘struct spinlock_t *’ but argument is of type ‘struct seqlock_t *’
	drivers/staging/pohmelfs/path_entry.c:49:2: warning: passing argument 1 of ‘rt_spin_unlock’ from incompatible pointer type [enabled by default]
	include/linux/spinlock_rt.h:22:56: note: expected ‘struct spinlock_t *’ but argument is of type ‘struct seqlock_t *’
	drivers/staging/pohmelfs/path_entry.c:95:2: warning: passing argument 1 of ‘rt_spin_lock’ from incompatible pointer type [enabled by default]
	include/linux/spinlock_rt.h:19:56: note: expected ‘struct spinlock_t *’ but argument is of type ‘struct seqlock_t *’

Hello Thomas,

you probably want to squash that into fs-struct-use-seqlock.patch
It's only compile tested.

Best regards
Uwe
