[ Upstream commit ea38f06e0291986eb93beb6d61fd413607a30ca4 ]

Currently when the call to fsp_reg_write fails -EIO is not being returned
because the count is being returned instead of the return value in retval.
Fix this by returning the value in retval instead of count.

Addresses-Coverity: ("Unused value")
Fixes: fc69f4a6af49 ("Input: add new driver for Sentelic Finger Sensing Pad")
