Subject: [PATCH v2 1/2] spi: spi-ti-qspi: Fix parameters order in regmap_update_bits calls
Date: Fri, 30 Mar 2018 11:41:23 +0200	[thread overview]
Message-ID: <1522402884-26790-1-git-send-email-arkadiusz.kwiatkowski@aptiv.com> (raw)
In-Reply-To: <496c162d-5e3c-e008-a14b-6b990e253e64@ti.com>

This commit fixes the order of parameters passed to regmap_update_bits
function inside spi-ti-qspi driver. Accidentally the code worked
correctly when cs=0, but it is not the case for other values.
