[ Upstream commit 43c633ef93a5d293c96ebcedb40130df13128428 ]
When building with 'make W=1', clang notices that the computed register values are never actually written back but instead the wrong variable is set:
drivers/dma/owl-dma.c:244:6: error: variable 'regval' set but not used [-Werror,-Wunused-but-set-variable] 244 | u32 regval; | ^ drivers/dma/owl-dma.c:268:6: error: variable 'regval' set but not used [-Werror,-Wunused-but-set-variable] 268 | u32 regval; | ^
Change these to what was most likely intended.
