Subject[PATCH -next v3] misc: rtsx: fix build for CONFIG_PM not set
Date
When CONFG_WERROR=y and CONFIG_PM is not set, there are fatal build
errors, so use appropriate macros for SYSTEM_SLEEP and RUNTIME_SLEEP
PM_OPS to prevent these. The #ifdef CONFIG_PM / #endif blocks
can also be removed since any dead code will be dropped by them.

../drivers/misc/cardreader/rtsx_pcr.c:1057:13: error: ‘rtsx_enable_aspm’ defined but not used [-Werror=unused-function]
static void rtsx_enable_aspm(struct rtsx_pcr *pcr)
miscread001.out:../drivers/misc/cardreader/rtsx_pcr.c:1065:13: error: ‘rtsx_comm_pm_power_saving’ defined but not used [-Werror=unused-function]
miscread001.out: static void rtsx_comm_pm_power_saving(struct rtsx_pcr *pcr)
../drivers/misc/cardreader/rtsx_pcr.c:1084:13: error: ‘rtsx_pm_power_saving’ defined but not used [-Werror=unused-function]

v3: Use SYSTEM_SLEEP_PM_OPS() and RUNTIME_PM_OPS() to avoid the build
errors. This eliminates the need for #ifdef CONFIG_PM/#endif
blocks of code and of __maybe_unused.
