[PATCH] spi: pic32-sqi: silence array overflow warning

From: Dan Carpenter
Date: Fri Apr 22 2016 - 05:55:24 EST


We read one element beyond the end of the array when we access
"rdesc[i + 1]" so it causes a static checker warning. It's harmless
because we write over it again on the next line. But let's just silence
the warning.
