From f9ef8dedee34e2d7828d5a6a0643cd969aaa8437 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 8 Dec 2025 03:07:30 +0100 Subject: [PATCH] dmaengine: dw-edma: Fix confusing cleanup.h syntax 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.
