[PATCH RT 2/4] rtmutex: Fix rt_mutex_timed_fastlock() slowfn type mismatch up to 3.10

[Ben Hutchings <ben@decadent.org.uk>]

[-- Attachment #1: Type: text/plain, Size: 1721 bytes --]

The type of the slowfn parameter is declared incorrectly in some of
the backports, resulting in:

kernel/rtmutex.c: In function 'rt_mutex_timed_futex_lock':
kernel/rtmutex.c:1730:12: warning: passing argument 5 of 'rt_mutex_timed_fastlock' from incompatible pointer type [enabled by default]
kernel/rtmutex.c:1655:1: note: expected 'int (*)(struct rt_mutex *, int,  struct hrtimer_sleeper *, int)' but argument is of type 'int (*)(struct rt_mutex *, int,  struct hrtimer_sleeper *, enum rtmutex_chainwalk)'
kernel/rtmutex.c: In function 'rt_mutex_timed_lock':
kernel/rtmutex.c:1770:12: warning: passing argument 5 of 'rt_mutex_timed_fastlock' from incompatible pointer type [enabled by default]

All the simple programs have been written, and all the good names taken.
