David Brownell 082c8cb4e5 spi device setup gets better error checking ... This updates some error reporting paths in SPI device setup: - Move validation logic for SPI chipselects to spi_new_device(), which is where it should always have been. - In spi_new_device(), emit error messages if the device can't be created. This is LOTS better than a silent failure; though eventually, the calling convention should probably change to use the <linux/err.h> conventions. - Includes one previously-missing check: SPI masters must always have at least one chipselect, even for dedicated busses which always keep it selected! It also adds a FIXME (IDR for dynamic ID allocation) so the issue doesn't live purely in my mailbox.
