2025-05-01drm/msm: Convert comma to semicolonChen Ni
Replace comma between expressions with semicolons. Using a ',' in place of a ';' can have unintended side effects. Although that is not the case here, it is seems best to use ';' unless ',' is intended. Found by inspection. No functional change intended. Compile tested only.

This actually reverts 86e92eeeb237 ("bcachefs: Annotate struct bch_xattr with __counted_by()"). After the x_name, there is a value. According to the disscussion[1], __counted_by assumes that the flexible array member contains exactly the amount of elements that are specified. Now there are users came across a false positive detection of an out of bounds write caused by the __counted_by here[2], so revert that.

2025-05-02spi: tegra114: Don't fail set_cs_timing when delays are zeroAaron Kling
The original code would skip null delay pointers, but when the pointers were converted to point within the spi_device struct, the check was not updated to skip delays of zero. Hence all spi devices that didn't set delays would fail to probe.

In case of complex pipelines (e.g. the forthcoming quad-pipe) the DPU might use more that one MERGE_3D block for a single output. Follow the pattern and extend the CTL_MERGE_3D_ACTIVE active register instead of simply writing new value there. Currently at most one MERGE_3D block is being used, so this has no impact on existing targets.

2025-05-01tracing: Fix trace_adjust_address() when there is no modules in scratch areaSteven Rostedt
The function trace_adjust_address() is used to map addresses of modules stored in the persistent memory and are also loaded in the current boot to return the current address for the module. If there's only one module entry, it will simply use that, otherwise it performs a bsearch of the entry array to find the modules to offset with. The issue is if there are no modules in the array. The code does not account for that and ends up referencing the first element in the array which does not exist and causes a crash. If nr_entries is zero, exit out early as if this was a core kernel address.

2025-05-01drm/i915/slpc: Balance the inc/dec for num_waitersVinay Belgaumkar
As seen in some recent failures, SLPC num_waiters value is < 0. This happens because the inc/dec are not balanced. We should skip decrement for the same conditions as the increment. Currently, we do that for power saving profile mode. This patch also ensures that num_waiters is incremented in the case min_softlimit is at boost freq. It ensures that we don't reduce the frequency while this request is in flight. v2: Add Fixes tags Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/13598 Fixes: f864a29afc32 ("drm/i915/slpc: Optmize waitboost for SLPC") Fixes: 4a82ceb04ad4 ("drm/i915/slpc: Add sysfs for SLPC power profiles") Cc: Sk Anirban <sk.anirban@intel.com> Reviewed-by: Sk Anirban <sk.anirban@intel.com> Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Link: https://lore.kernel.org/r/20250428183555.3250021-1-vinay.belgaumkar@intel.com
