From: Dan Carpenter Date: Tue, 11 Feb 2014 21:07:55 +0000 (+0300) Subject: w1: small type cleanup in sysfs X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a7155f4e2252be167fa69468e11b19a3fac5e625;p=deliverable%2Flinux.git w1: small type cleanup in sysfs On 64 bit systems, a large value for "long tmp" is truncated when assigning to "int md->max_slave_count" so we still end up with a value less than one despite the "tmp < 1" check. This is more of a problem for static checkers than a real life issue, but it's simple enough to fix.
