coresight: cti-sysfs: Mark coresight_cti_reg_store() as __maybe_unused
When building without CONFIG_CORESIGHT_CTI_INTEGRATION_REGS, there is a
warning about coresight_cti_reg_store() being unused in the file:
drivers/hwtracing/coresight/coresight-cti-sysfs.c:184:16: warning: 'coresight_cti_reg_store' defined but not used [-Wunused-function]
184 | static ssize_t coresight_cti_reg_store(struct device *dev,
| ^~~~~~~~~~~~~~~~~~~~~~~
This is expected as coresight_cti_reg_store() is only used in the
coresight_cti_reg_rw macro, which is only used in a block guarded by
CONFIG_CORESIGHT_CTI_INTEGRATION_REGS. Mark coresight_cti_reg_store() as
__maybe_unused to clearly indicate that the function may be unused
depending on the configuration.
