-Subject: [PATCH] w1: ds2413: fix state byte comparision
-
-commit aacd152ecd7b18af5d2d96dea9e7284c1c93abea upstream.
-
-This commit is fixing a smatch warning:
-drivers/w1/slaves/w1_ds2413.c:61 state_read() warn: impossible condition '(*buf == 255) => ((-128)-127 == 255)'
-by creating additional u8 variable for the bus reading and comparision
-
-Reported-by: kbuild test robot <lkp@intel.com>
-Reported-by: Dan Carpenter <dan.carpenter@oracle.com>
-Cc: Dan Carpenter <dan.carpenter@oracle.com>
-Fixes: 3856032a0628 ("w1: ds2413: when the slave is not responding during read, select it again")
