4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit bd7e31bbade02bc1e92aa00d5cf2cee2da66838a upstream.
gcc-7 suggests that an expression using a bitwise not and a bitmask on a 'bool' variable is better written using boolean logic:
drivers/media/rc/imon.c: In function 'imon_incoming_scancode': drivers/media/rc/imon.c:1725:22: error: '~' on a boolean expression [-Werror=bool-operation] ictx->pad_mouse = ~(ictx->pad_mouse) & 0x1; ^ drivers/media/rc/imon.c:1725:22: note: did you mean to use logical not?
I agree.
Fixes: 21677cfc562a ("V4L/DVB: ir-core: add imon driver")
