Hello there, drivers/staging/media/ipu3/ipu3-css.c:1831:30: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] Source code is css->pipes[pipe].bindex = ipu3_css_find_binary(css, pipe, q, r); if (css->pipes[pipe].bindex < 0) { dev_err(css->dev, "failed to find suitable binary\n"); return -EINVAL; } Suggest sanity check return value from function first, then if it is ok, assign it to an unsigned variable.
