Subject: [PATCH v1 0/3] spi: Add more consistency to CS handle

There are the following issues with the current code:
- inconsistent use of 0xFF and -1 for invalid chip select pin
- inconsistent plain or BIT() use with a hard-to-understand comment
- wrong types used for last_cs_* fields

Fix all of these here.

Andy Shevchenko (3):
  spi: Consistently use BIT for cs_index_mask
  spi: Fix types of the last chip select storage variables
  spi: Introduce SPI_INVALID_CS and is_valid_cs()
