2025-03-26fbdev: omapfb: Add 'plane' value checkLeonid Arapov
Function dispc_ovl_setup is not intended to work with the value OMAP_DSS_WB of the enum parameter plane. The value of this parameter is initialized in dss_init_overlays and in the current state of the code it cannot take this value so it's not a real problem. For the purposes of defensive coding it wouldn't be superfluous to check the parameter value, because some functions down the call stack process this value correctly and some not. For example, in dispc_ovl_setup_global_alpha it may lead to buffer overflow. Add check for this value. Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.

Value of enum parameter 'plane' is initialized in dss_init_overlays and cannot take the value OMAP_DSS_WB. Function dispc_ovl_setup_common could be called with this value of parameter only from dispc_wb_setup, which has never been used and has been removed in commit 4f55bb03801a ("omapfb: Remove unused writeback code").

2025-01-12fbdev: omapfb: Use syscon_regmap_lookup_by_phandle_argsKrzysztof Kozlowski
Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over syscon_regmap_lookup_by_phandle() combined with getting the syscon argument. Except simpler code this annotates within one line that given phandle has arguments, so grepping for code would be easier. There is also no real benefit in printing errors on missing syscon argument, because this is done just too late: runtime check on static/build-time data. Dtschema and Devicetree bindings offer the static/build-time check for this already. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Helge Deller <deller@gmx.de>

2025-01-09fbdev: omapfb: Fix an OF node leak in dss_of_port_get_parent_device()Joe Hattori
dss_of_port_get_parent_device() leaks an OF node reference when i >= 2 and struct device_node *np is present. Since of_get_next_parent() obtains a reference of the returned OF node, call of_node_put() before returning NULL. This was found by an experimental verifier that I am developing, and no runtime test was able to be performed due to that lack of actual devices.

2024-10-08fbdev: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/video/fbdev to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

2023-04-24fbdev: omapfb: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2020-07-10omapfb: dss: Fix max fclk divider for omap36xxAdam Ford
The drm/omap driver was fixed to correct an issue where using a divider of 32 breaks the DSS despite the TRM stating 32 is a valid number. Through experimentation, it appears that 31 works, and it is consistent with the value used by the drm/omap driver. This patch fixes the divider for fbdev driver instead of the drm.
