Subject: [PATCH 2/2] raw: set range for MAX_RAW_DEVS
Date: Tue, 04 Feb 2014 23:23:40 +0100 [thread overview]
Message-ID: <1391552620.13156.16.camel@x220> (raw)
The Kconfig symbol MAX_RAW_DEVS is meant to be between 1 and 65536. But
those boundaries are not enforced by its Kconfig entry.
Note that MAX_RAW_DEVS is used to set MAX_RAW_MINORS in
drivers/char/raw.c. If one would accidentally set MAX_RAW_DEVS to an
invalid value, that invalid value will actually end up being used in
raw_init().
So add an appropriate range to this Kconfig entry.
