[PATCH 1/1] staging: iio: initialize data pointer before using it

From: Nicolas Iooss
Date: Sat Jun 18 2016 - 17:13:39 EST


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").
