Subject: [PATCH] spi: pxa2xx: Remove redundant call to lpss_ssp_setup() in probe
Date: Fri, 20 Nov 2015 13:55:21 +0200	[thread overview]
Message-ID: <1448020521-94914-1-git-send-email-mika.westerberg@linux.intel.com> (raw)

Commit 8b136baa5892 ("spi: pxa2xx: Detect number of enabled Intel LPSS SPI
chip select signals") added a block where lpss_ssp_setup() gets called
again for Intel LPSS SPI host controllers before checking number of chip
selects from the capabilities register.

There is no point in calling the function twice in probe so remove the
first call.
