[PATCH 2/2] dmaengine: ppc4xx: remove xor_hw_desc assignment without reading
From: Krzysztof Kozlowski
Date: Mon Oct 19 2020 - 12:00:18 EST
The xor_hw_desc local variable is assigned but never read:
drivers/dma/ppc4xx/adma.c: In function ‘ppc440spe_desc_set_src_mult’:
drivers/dma/ppc4xx/adma.c:562:17: warning: variable ‘xor_hw_desc’ set but not used [-Wunused-but-set-variable]
