Subject: cxl: Rename region_res_match_cxl_range() to spa_maps_hpa()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c43521b9db7f5ed481cfdfb04ad2e7fe0cb9dcf5;p=thirdparty%2Fkernel%2Fstable.git

cxl: Rename region_res_match_cxl_range() to spa_maps_hpa()

The function name region_res_match_cxl_range() does not accurately
convey the operation of address comparison with cache size. Rename
to spa_maps_hpa() to provide a better function name.
