Subject: spi: pxa2xx: Move number of CS pins validation out of condition
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=df3431fd379dcc3b231bd109a55948c27474478d;p=linux.git

spi: pxa2xx: Move number of CS pins validation out of condition

There is no need to allocate chip_data and then validate number of
CS pins as it will have the same effect. Hence move number of CS pins
validation out of condition in setup().
