Subject: [PATCH] spi: sun4i: update max transfer size reported
Date: Mon, 27 Jul 2020 17:23:28 +1000	[thread overview]
Message-ID: <20200727072328.510798-1-net147@gmail.com> (raw)

The spi-sun4i driver already has the ability to do large transfers.
However, the max transfer size reported is still fifo depth - 1.

Update the max transfer size reported to the max value possible.

Fixes: 196737912da5 ("spi: sun4i: Allow transfers larger than FIFO size")
