File raiden_debug_spi.c:

PS1, Line 1599: 	spi_config->data = data; /* data is needed to configure protocol below */
Maybe worth to mention in the commit message, that this is not
needed anymore, because register_spi_master() will do it later.

PS1, Line 1327: struct raiden_debug_spi_data *ctx_data =
              : 		(struct raiden_debug_spi_data *)data;
No cast necessary, it already has that type. Or...

alternatively, just name the parameter `ctx_data`?
