Subject: [PATCH 06/17] ioctl: make argc counters unsigned
Use unsigned int for cmd_context::argc and local variables used for
command line argument count. These counters may never get negative and are
often compared to unsigned expressions.
Signed-off-by: Michal Kubecek <mkubecek@suse.cz>
Reviewed-by: Andrew Lunn <andrew@lunn.ch>
(cherry picked from commit 519f95bd59034e672cfbac70ca8d7badc4f26cc7)
