The quilt patch titled
     Subject: zram: remove KMSG_COMPONENT macro
has been removed from the -mm tree.  Its filename was

of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: zram: remove KMSG_COMPONENT macro
Date: Wed, 26 Nov 2025 15:36:02 +0100

The KMSG_COMPONENT macro is a leftover of the s390 specific "kernel
message catalog" from 2008 [1] which never made it upstream.

The macro was added to s390 code to allow for an out-of-tree patch which
used this to generate unique message ids.  Also this out-of-tree doesn't
exist anymore.

The pattern of how the KMSG_COMPONENT is used was partially also used for
non s390 specific code, for whatever reasons.

Remove the macro in order to get rid of a pointless indirection.
