treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

fbdev: omapfb: Add 'plane' value check

2025-03-26T21:39:21+00:00

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.

fbdev: omapfb: Remove writeback deadcode

2025-03-26T21:39:21+00:00

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"). The code in the if-branch is unreachable. Remove unreachable branch. Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.

fbdev: omapfb: Use syscon_regmap_lookup_by_phandle_args

2025-01-12T17:12:35+00:00

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 Signed-off-by: Helge Deller

fbdev: omapfb: Use of_property_present() to test existence of DT property

fbdev: omapfb: Fix an OF node leak in dss_of_port_get_parent_device()

2025-01-08T23:35:09+00:00

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.
