[PATCH][next] spi: loopback-test: make several module parameters static

From: Colin King
Date: Tue Jul 18 2017 - 08:42:38 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Several module parameters are local to the source, so make them
static. Cleans up several sparse warnings such as:

"symbol 'loop_req' was not declared. Should it be static?"
