+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")
