Subject[PATCH 1/1] staging: iio: initialize data pointer before using it
Date
ad7606_spi_read_block() reads SPI big-endian data into a buffer which is
then converted to CPU byte-order with a second variable. This variable,
data, has been left unitialized after commit 87787e5ef727 ("Staging:
iio: Fix sparse endian warning").

Signed-off-by: Nicolas Iooss <nicolas.iooss_linux@m4x.org>
