From 2130be57d5eb01bcd440495cdb5455cf40468f0c Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Mon, 6 Jul 2020 16:34:37 +0200 Subject: spi: spi-sun6i: sun6i_spi_transfer_one(): remove not needed masking of transfer length In sun6i_spi_transfer_one() the driver ensures that the length of the transfer is smaller or equal to SUN6I_MAX_XFER_SIZE. This means the masking of the length to SUN6I_MAX_XFER_SIZE can be skipped when writing the transfer length into the registers. This patch removes the useless masking of the transfer length to SUN6I_MAX_XFER_SIZE.
