   4 Subject: [PATCH] nvmem: lan9662-otp: Change return type of
   5  lan9662_otp_wait_flag_clear()
   6
   7 The blamed commit introduced the following smatch warning in the
   8 function lan9662_otp_wait_flag_clear:
   9 drivers/nvmem/lan9662-otpc.c:43 lan9662_otp_wait_flag_clear() warn: signedness bug returning '(-110)'
  10
  11 Fix this by changing the return type of the function
  12 lan9662_otp_wait_flag_clear() to be int instead of bool.
  13
  14 Fixes: 9e8f208ad5229d ("nvmem: lan9662-otp: add support")
