Subject[PATCH][next] staging: wfx: fix uninitialized variable bytes_done
Date
From: Colin Ian King <colin.king@canonical.com>

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")
