2019-01-14drm: bridge: Constify mode arguments to bridge .mode_set() operationLaurent Pinchart1-1/+1
The mode and ajusted_mode passed to the bridge .mode_set() operation should never be modified by the bridge (and are not in any of the existing bridge drivers). Make them const to make this clear.

2018-01-09drm/bridge/synopsys: stop clobbering drvdataBrian Norris1-5/+9
Bridge drivers/helpers shouldn't be clobbering the drvdata, since a parent driver might need to own this. Instead, let's return our 'dw_mipi_dsi' object and have callers pass that back to us for removal.

devm_ioremap_resource() already checks if the resource is NULL, so remove the unnecessary platform_get_resource() error check.

2017-09-08drm/stm: fix warning about multiplication in conditionArnd Bergmann1-3/+5
gcc-7 complains about multiplying within a condition being suspicious: drivers/gpu/drm/stm/dw_mipi_dsi-stm.c: In function 'dsi_pll_get_clkout_khz': drivers/gpu/drm/stm/dw_mipi_dsi-stm.c:117:10: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context] The code here is correct, but can be easily rephrased to make that more obvious. I also swap out the error handling and the normal code path for clarity.
