Subject: [patch] iio: tsl2583: off by one in in_illuminance_lux_table_store()
Date: Fri, 18 Nov 2016 14:51:54 +0300	[thread overview]
Message-ID: <20161118115153.GC3281@mwanda> (raw)

The value[] array has "max_ints" elements so this should be >= instead
of >.

Fixes: ac4f6eee8fe8 ("staging: iio: TAOS tsl258x: Device driver")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
