*	FMC: fix locking in sample chardev driver	Alessandro Rubini	2013-07-25	1	-5/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	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: fix error handling in probe() function	Dan Carpenter	2013-06-25	1	-6/+11
\| \| \| \| \| \| \| \| \|	The call to kzalloc() wasn't checked. The dev_info() message dereferenced freed memory on error. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Alessandro Rubini <rubini@gnudd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
*	FMC: add a char-device mezzanine driver	Alessandro Rubini	2013-06-19	1	-0/+197
	This driver exports the memory area associated with the mezzanine card as a misc device, so users can access registers.
