From 76880b4015f7bdbe73bf2c07e42ef0ba7a343d3e Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 9 Feb 2016 09:14:12 -0200 Subject: [PATCH] [media] usb/cpia2_core: clean up a min_t() cast It makes sense to make the min_t() cast unsigned here since we don't really want negative sizes. Making it signed causes a static checker warning in Smatch. Smatch knows "fw->size - i" is positive but it doesn't know that fw->size is less than INT_MAX so in theory casting it to int might lead to a negative.
