Subject[PATCH 1/2] ARM: samsung: fix PM debug build with DEBUG_LL but !MMU
Date
Selecting CONFIG_SAMSUNG_PM_DEBUG (depending on CONFIG_DEBUG_LL) but
without CONFIG_MMU leads to build errors:

arch/arm/plat-samsung/pm-debug.c: In function ‘s3c_pm_uart_base’:
arch/arm/plat-samsung/pm-debug.c:57:2: error:
implicit declaration of function ‘debug_ll_addr’ [-Werror=implicit-function-declaration]

Reported-by: kernel test robot <lkp@intel.com>
Fixes: 99b2fc2b8b40 ("ARM: SAMSUNG: Use debug_ll_addr() to get UART base address")
Cc: <stable@vger.kernel.org>
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

Patchset is rebased on v5.9-rc1.

Say Y here if you want verbose debugging from the PM Suspend and
Resume code. See <file:Documentation/arm/samsung-s3c24xx/suspend.rst>
