[PATCH] spi: misc fixes
This collects some small SPI patches that seem to be missing from the MM tree:
- spi_butterfly kbuild hooks got dropped somehow; this restores them
- quick fix for a (theoretical?) m25p80_write() oops noted by Andrew
- quick fix for a potential config-specific oops for mtd_dataflash()
- minor doc tweaks
