Subject: amdgpu: Use uint32_t i in amdgpu_find_bo_by_cpu_mapping
X-Git-Tag: libdrm-2.4.94~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1e12c16d7697a1223630a507c1032d940794039a;p=platform%2Fupstream%2Flibdrm.git

amdgpu: Use uint32_t i in amdgpu_find_bo_by_cpu_mapping

The compiler points out that an int doesn't work as intended if
dev->bo_handles.max_key > INT_MAX:

../../amdgpu/amdgpu_bo.c: In function ‘amdgpu_find_bo_by_cpu_mapping’:
../../amdgpu/amdgpu_bo.c:550:16: warning: comparison of integer expressions of different signedness: ‘int’ and ‘uint32_t’ {aka ‘unsigned int’} [-Wsign-compare]
  for (i = 0; i < dev->bo_handles.max_key; i++) {
                ^
../../amdgpu/amdgpu_bo.c:558:8: warning: comparison of integer expressions of different signedness: ‘int’ and ‘uint32_t’ {aka ‘unsigned int’} [-Wsign-compare]
  if (i < dev->bo_handles.max_key) {
        ^

                     (v2)")
