[PATCH 1/2] drm/tests: Fix endian warning

From: José Expósito
Date: Mon Jun 30 2025 - 05:01:13 EST


When compiling with sparse enabled, this warning is thrown:

warning: incorrect type in argument 2 (different base types)
expected restricted __le32 const [usertype] *buf
got unsigned int [usertype] *[assigned] buf

Add a cast to fix it.

Fixes: 453114319699 ("drm/format-helper: Add KUnit tests for drm_fb_xrgb8888_to_xrgb2101010()")
