X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=50d69b5184169caeb85e082f627200da9b0e1677;p=openwrt%2Fstaging%2Fblogic.git

iio: Fix iio_buffer_register stub signature

Match the iio_buffer_register stub signature up to the real function and make
the second parameter const. This fixes a the following warnings if
CONFIG_IIO_BUFFER is disabled:

	drivers/staging/iio/accel/adis16201_core.c: In function ‘adis16201_probe’:
