watchdog: diag288_wdt: Remove KMSG_COMPONENT macro

hcahca · hcahca · commit 283f90b50de0 · 2025-11-26T17:34:52.000+01:00
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. Remove the macro in order to get rid of a pointless indirection. [1] https://lwn.net/Articles/292650/ Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
