X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0b863b333f529c7ddd8bee58e6696a7254417a05;p=linux-beck.git drivers, pch_dma: Fix warning when CONFIG_PM=n. When CONFIG_PM=n, we get the following warning: drivers/dma/pch_dma.c:741: warning: ‘pch_dma_suspend’ defined but not used drivers/dma/pch_dma.c:755: warning: ‘pch_dma_resume’ defined but not used To fix it, wrap pch_dma_{suspend,resume} and pch_dma_{save,restore}_regs functions with CONFIG_PM.
