memory: samsung: exynos5422-dmc: Do not ignore return code of regmap_read()

2020-08-19T06:23:36Z

[ Upstream commit c4f16e96d8fdd62ef12898fc0965c42093bed237 ] Check for regmap_read() return code before using the read value in following write in exynos5_switch_timing_regs(). Pass reading error code to the callers. This does not introduce proper error handling for such failed reads (and obviously regmap_write() error is still ignored) because the driver ignored this in all places. Therefor it only fixes reported issue while matching current driver coding style: drivers/memory/samsung/exynos5422-dmc.c: In function 'exynos5_switch_timing_regs': >> drivers/memory/samsung/exynos5422-dmc.c:216:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable] Reported-by: kernel test robot Signed-off-by: Krzysztof Kozlowski Signed-off-by: Sasha Levin

memory: tegra: Fix an error handling path in tegra186_emc_probe()

2020-08-19T06:23:27Z

[ Upstream commit c3d4eb3bf6ad32466555b31094f33a299444f795 ] The call to tegra_bpmp_get() must be balanced by a call to tegra_bpmp_put() in case of error, as already done in the remove function. Add an error handling path and corresponding goto.

memory: samsung: exynos5422-dmc: Fix tFAW timings alignment

2020-06-22T07:33:05Z

commit 4bff7214d263b5235263136cb53147a759b3f3ab upstream. Aligning of tFAW timing with standard was using wrong argument as minimum acceptable value. This could lead to wrong timing if provided timings and clock period do not match the standard.
