Subject: [PATCH] nvmem: lan9662-otp: Change return type of
lan9662_otp_wait_flag_clear()
The blamed commit introduced the following smatch warning in the
function lan9662_otp_wait_flag_clear:
drivers/nvmem/lan9662-otpc.c:43 lan9662_otp_wait_flag_clear() warn: signedness bug returning '(-110)'
Fix this by changing the return type of the function
lan9662_otp_wait_flag_clear() to be int instead of bool.
Fixes: 9e8f208ad5229d ("nvmem: lan9662-otp: add support")
