From: Arnd Bergmann <arnd@arndb.de> The slave device is picked through either devicetree or a filter function, and any remaining out-of-tree drivers would have warned about this usage since 2015. Stop interpreting the field finally so it can be removed from the interface. Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- drivers/dma/sh/shdma-base.c | 8 -------- 1 file changed, 8 deletions(-)
