We test whether a bit is set in a mask here, which is correct but gcc warns about it as it thinks it might be confusing:
drivers/isdn/isdnloop/isdnloop.c:412:37: error: ?: using integer constants in boolean context, the expression will always evaluate to 'true' [-Werror=int-in-bool-context]
This replaces the negation of an integer with an equivalent comparison to zero, which gets rid of the warning.
