[PATCH v2 5/5] spi: s3c64xx: use unsigned type for fifo handling variables

From: Andi Shyti
Date: Mon Jun 27 2016 - 22:43:12 EST


The 'quirks' variable cannot ever be negative, therefore use u8
instead of int. The 8 bit size is given from the fact that
currently the quirks variable has very few statuses.

The rx_lvl_offset and tx_st_done store shift values, so that u8
is a proper size.

fifo_lvl_mask stores a series of masks, to be in we will keep the
32 bit size.
