dpll: fix clock quality level reporting

2026-08-03T09:17:38+00:00

commit 70d99623d5c11e1a9bcc564b8fbad6fa916913d8 upstream. The DPLL_CLOCK_QUALITY_LEVEL_ITU_OPT1_EPRC is not reported via netlink due to bug in dpll_msg_add_clock_quality_level(). The usage of DPLL_CLOCK_QUALITY_LEVEL_MAX for both DECLARE_BITMAP() and for_each_set_bit() is not correct because these macros requires bitmap size and not the highest valid bit in the bitmap. Use correct bitmap size to fix this issue.

Commit fb3dda82fd38 ("net: airoha: Move airoha_eth driver in a dedicated folder") accidentally added the line: source "drivers/net/ethernet/mellanox/Kconfig" in drivers/net/ethernet/Kconfig, so that this line is duplicated in that file.

gpu: Fix uninitialized buddy for built-in drivers

2026-08-03T09:17:37+00:00

commit cc27314c67516c138ee3829197d1c3b998e29fae upstream. Move buddy to the start of the link order, so its __init runs before any other built-in drivers that may depend on it. Otherwise, a built-in driver that tries to use the buddy allocator will run into a kernel NULL pointer dereference because slab_blocks is uninitialized. Specifically, this fixes drm/xe (as built-in) running into a kernel panic during boot, because it uses buddy during device probe.

net/mlx5e: Fix NULL pointer dereference in ioctl module EEPROM query

2026-08-03T09:17:37+00:00

commit 7d36a4a8bf62dc508bc6bb4b59727aec25064ca5 upstream. The mlx5_query_mcia() function unconditionally dereferences the status pointer to store the MCIA register status value. However, mlx5e_get_module_id() passes NULL since it doesn't need the status value. Add a NULL check before dereferencing the status pointer to prevent a NULL pointer dereference.

usb: musb: omap2430: Do not put borrowed of_node in probe

2026-08-03T09:17:37+00:00

commit c947360ae63eee1c9eacc030dd6f5a53f717addf upstream. omap2430_probe() stores pdev->dev.of_node in a local np variable. This is a borrowed pointer and the probe function does not take a reference to it. The success and error paths nevertheless call of_node_put(np). This drops a reference that is owned by the platform device, and can leave pdev->dev.of_node with an unbalanced reference count. Do not put the borrowed platform device node from omap2430_probe(). References taken for the child MUSB device are handled by the device core, and the ctrl-module phandle reference is still released separately.

usb: musb: omap2430: clean up probe error handling

commit 51d4b0a44c82e5eff056ef76acd2c3c605a8eb74 upstream. Using numbered error labels is discouraged (e.g. as it requires renumbering them when adding a new intermediate error path). Rename the error labels after what they do. While at it, drop the redundant platform allocation failure dev_err() as the error would already have been logged by the allocator.

[ Upstream commit 5b6dc50e9ed870fffbf2ae6de77b30fb0d15eab8 ] Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.
