[OpenWrt-Devel] [PATCH v2 uqmi] Add command for listing device capabilities

[Sławomir Demeszko]

Sorry, it seems my compiler doesn't suport -Wtautological-compare option,
and I was not warned about this. This condition could be removed, but
as I read it is unspecified if enums are signed or unsigned, it depends
on compiler, so I cast it to signed for comparison. I can't test it,
but should get rid of the warning.
