[PATCH 07/32] staging: gasket: Return EBUSY on mapping create when already in use

[Todd Poynor]

From: Todd Poynor <toddpoynor@xxxxxxxxxx>

gasket_sysfs_create_mapping() return EBUSY if sysfs mapping already in
use, as a more appropriate error code than the current return of EINVAL,
which would indicate invalid parameters.
