The fmc-chardev module was over-locking, by calling misc
register/unregister while holding its spinlock.  This reported a
"scheduling while atomic" error.

Since the misc driver already serializes operations internally, this
commit downgrades the fmc-chardev lock to just cover its own list.

FMC bus is part of the recent kernel versions, so we may have conflicts
between this version and the one in the kernel.

With this patch we force the compilation proceed to ignore the kernel

Sometimes (expecially in cross-compilation context) t is necessary to use
