From: Matt Roper Date: Fri, 24 Oct 2025 20:08:35 +0000 (-0700) Subject: drm/xe/configfs: Drop MAX_GT_TYPE_CHARS constant X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=fab36494f26c1818f0d02230f30aca45b4888848;p=thirdparty%2Fkernel%2Flinux.git drm/xe/configfs: Drop MAX_GT_TYPE_CHARS constant Early revisions of commit 7abd69278bb5 ("drm/xe/configfs: Add attribute to disable GT types") used MAX_GT_TYPE_CHARS not only to size the constant name field, but also for some of the string matching logic. By the time the patch finally landed, the constant was no longer needed for parsing. Stop using it for the string field definition as well; this eliminates the risk that we forget to update the constant if we ever add a GT type name longer than seven characters.
