    mutex: drop "inline" from mutex_lock() inside kernel/mutex.c · b09d2501

    Impact: build fix
    
    mutex_lock() is was defined inline in kernel/mutex.c, but wasn't
    declared so not in <linux/mutex.h>.  This didn't cause a problem until
    checkin 3a2d367d9aabac486ac4444c6c7ec7a1dab16267 added the
    atomic_dec_and_mutex_lock() inline in between declaration and
    definion.
    
    This broke building with CONFIG_ALLOW_WARNINGS=n, e.g. make
    allnoconfig.
    
    Either from the source code nor the allnoconfig binary output I cannot
    find any internal references to mutex_lock() in kernel/mutex.c, so
    presumably this "inline" is now-useless legacy.
