ARM: omap2: Fix reference count leaks in omap_control_init()

2026-04-18T08:30:50+00:00

[ Upstream commit 93a04ab480c8bbcb7d9004be139c538c8a0c1bc8 ] The of_get_child_by_name() function increments the reference count of child nodes, causing multiple reference leaks in omap_control_init(): 1. scm_conf node never released in normal/error paths 2. clocks node leak when checking existence 3. Missing scm_conf release before np in error paths Fix these leaks by adding proper of_node_put() calls and separate error handling.

ARM: clean up the memset64() C wrapper

2026-04-18T08:30:49+00:00

[ Upstream commit b52343d1cb47bb27ca32a3f4952cc2fd3cd165bf ] The current logic to split the 64-bit argument into its 32-bit halves is byte-order specific and a bit clunky. Use a union instead which is easier to read and works in all cases. GCC still generates the same machine code. While at it, rename the arguments of the __memset64() prototype to actually reflect their semantics.

ARM: 9467/1: mm: Don't use %pK through printk

2026-03-04T12:20:07+00:00

[ Upstream commit 012ea376a5948b025f260aa45d2a6ec5d96674ea ] Restricted pointers ("%pK") were never meant to be used through printk(). They can acquire sleeping locks in atomic contexts. Switch to %px over the more secure %p as this usage is a debugging aid, gated behind CONFIG_DEBUG_VIRTUAL and used by WARN().

power: supply: wm97xx_battery: Convert to GPIO descriptor

2026-03-04T12:19:38+00:00

[ Upstream commit cb6d6918c56ffd98e88164d5471f692d33dabf2b ] This converts the WM97xx driver to use a GPIO descriptor instead of passing a GPIO number thru platform data. Like everything else in the driver, use a simple local variable for the descriptor, it can only ever appear in one instance anyway so it should not hurt. After converting the driver I noticed that none of the boardfiles actually define a meaningful GPIO line for this, but hey, it is converted.

ARM: dts: allwinner: sun5i-a13-utoo-p66: delete "power-gpios" property

2026-03-04T12:19:27+00:00

[ Upstream commit 0b2761eb1287bd9f62367cccf6626eb3107cef6f ] The P66's device tree includes the reference design dtsi files, which defines a node and properties for the touchpanel in the common design. The P66 dts file then overrides all the properties to match its own design, but as the touchpanel model is different, a different schema is matched. This other schema uses a different name for the GPIO. The original submission added the correct GPIO property, but did not delete the one inherited from the reference design, causing validation errors. Explicitly delete the incorrect GPIO property.
