[PATCH][next] drm/bridge: sii902x: fix comparision of u32 with less than zero

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The less than check for the variable num_lanes is always going to be
false because the variable is a u32.  Fix this by making num_lanes an
int and also make loop index i an int too.

Addresses-Coverity: ("Unsigned compared against 0")
Fixes: ff5781634c41 ("drm/bridge: sii902x: Implement HDMI audio support")
