From: Kevin Hao <kexin....@windriver.com>
A new CS_MODE_READ_PREVBOOT mode was introduced by commit e86129e38029
("coresight: tmc: etr: Add support for Marvell OcteonTX2"), but it was
not added in switch of etm4_disable(). This would emit a build error
like below when CONFIG_WERROR is enabled:
drivers/hwtracing/coresight/coresight-etm4x-core.c: In function
‘etm4_disable’:
drivers/hwtracing/coresight/coresight-etm4x-core.c:1050:9: error: enumeration
value ‘CS_MODE_READ_PREVBOOT’ not handled in switch [-Werror=switch]
1050 | switch (mode) {
| ^~~~~~
cc1: all warnings being treated as errors
