s390/cpum_cf,perf: change DFLT_CCERROR counter name
Change the counter name DLFT_CCERROR to DLFT_CCFINISH on IBM z15. This counter counts completed DEFLATE instructions with exit code 0, 1 or 2. Since exit code 0 means success and exit code 1 or 2 indicate errors, change the counter name to avoid confusion. This counter is incremented each time the DEFLATE instruction completed regardless if an error was detected or not. Fixes: d68d5d51dc89 ("s390/cpum_cf: Add new extended counters for IBM z15") Fixes: e7950166e402 ("perf vendor events s390: Add new deflate counters for IBM z15") Cc: stable@vger.kernel.org # v5.7 Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Reviewed-by: Sumanth Korikkar <sumanthk@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
