Subject: spi: dw-mid: fix FIFO size
From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
commit 67bf9cda4b498b8cea4a40be67a470afe57d2e88 upstream.
The FIFO size is 40 accordingly to the specifications, but this means 0x40,
i.e. 64 bytes. This patch fixes the typo and enables FIFO size autodetection
for Intel MID devices.
Fixes: 7063c0d942a1 (spi/dw_spi: add DMA support)
