[PATCH] spi/sirf: fix error propagation in spi_sirfsoc_probe()

[Barry Song]

2013/6/6 Alexey Khoroshilov <khoroshilov at ispras.ru>:
> If pinctrl_get_select_default() fails, spi_sirfsoc_probe()
> returns IS_ERR(sspi->p) instead of PTR_ERR(sspi->p).
>
> Found by Linux Driver Verification project (linuxtesting.org).
