Subject: [PATCH] spi: ath79: remove spi-master setup and cleanup assignment
Date: Tue,  3 Mar 2020 22:56:18 +0100	[thread overview]
Message-ID: <> (raw)

This removes the assignment of setup and cleanup functions for the ath79
target. Assigning the setup-method will lead to 'setup_transfer' not
being assigned in spi_bitbang_init. Because of this, performing any
TX/RX operation will lead to a kernel oops.

Also drop the redundant cleanup assignment, as it's also assigned in
