From 7f8226887c28267d3c2351692d4429ead1e17695 Mon Sep 17 00:00:00 2001 From: Philip Elcan Date: Wed, 29 Aug 2018 15:46:12 -0400 Subject: gpu: nvgpu: cleanup return types for MISRA 10.3 This is a big cleanup of return types across a number of modules in the nvgpu driver. Many functions were returning u32 but using negative return codes. This is a MISRA 10.3 violation by assigning signed values to a u32.
