2025-12-17serial: 8250_dw: handle clock enable errors in runtime_resumeArtem Shimko1-2/+9
Add error checking for clk_prepare_enable() calls in dw8250_runtime_resume(). Currently if either clock fails to enable, the function returns success while leaving clocks in inconsistent state. This change implements comprehensive error handling by checking the return values of both clk_prepare_enable() calls. If the second clock enable operation fails after the first clock has already been successfully enabled, the code now properly cleans up by disabling and unpreparing the first clock before returning. The error code is then propagated to the caller, ensuring that clock enable failures are properly reported rather than being silently ignored.

2025-12-13x86/hv: Add gitignore entry for generated header fileLinus Torvalds1-0/+1
Commit 7bfe3b8ea6e3 ("Drivers: hv: Introduce mshv_vtl driver") added a new generated header file for the offsets into the mshv_vtl_cpu_context structure to be used by the low-level assembly code. But it didn't add the .gitignore file to go with it, so 'git status' and friends will mention it. Let's add the gitignore file before somebody thinks that generated header should be committed.

2025-12-13i3c: adi: Fix confusing cleanup.h syntaxKrzysztof Kozlowski1-6/+4
Initializing automatic __free variables to NULL without need (e.g. branches with different allocations), followed by actual allocation is in contrary to explicit coding rules guiding cleanup.h: "Given that the "__free(...) = NULL" pattern for variables defined at the top of the function poses this potential interdependency problem the recommendation is to always define and assign variables in one statement and not group variable definitions at the top of the function when __free() is used." Code does not have a bug, but is less readable and uses discouraged coding practice, so fix that by moving declaration to the place of assignment.
