Subject: Input: ad7877 - use spi_get_drvdata() and spi_set_drvdata()
X-Git-Tag: v4.6-rc1~9^2~918
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e1793c69c82626717257285f437b0da7ad0d2e99;p=platform%2Fkernel%2Flinux-exynos.git

Input: ad7877 - use spi_get_drvdata() and spi_set_drvdata()

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.
