[PATCH][next] staging: wfx: fix uninitialized variable bytes_done
From: Colin King
Date: Mon Jul 06 2020 - 09:20:23 EST
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The variable bytes_done is not initialized and hence the first
FIFO size check on bytes_done may be breaking prematurely from
the loop if bytes_done contains a large bogus uninitialized value.
Fix this by initializing bytes_done to zero.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: a9408ad79ff3 ("staging: wfx: load the firmware faster")
