[PATCH AUTOSEL for 4.9 142/219] regulator: isl9305: fix array size
From: Sasha Levin
Date: Sat Mar 03 2018 - 17:35:35 EST
From: Vincent Stehlà <vincent.stehle@xxxxxxxxxxx>
[ Upstream commit 0c08aaf873174c95e674cf21ffcd041c589d2e5b ]
ISL9305_MAX_REGULATOR is the last index used to access the init_data[]
array, so we need to add one to this last index to obtain the necessary
array size.
This fixes the following smatch error:
drivers/regulator/isl9305.c:160 isl9305_i2c_probe() error: buffer overflow 'pdata->init_data' 3 <= 3
Fixes: dec38b5ce6a9edb4 ("regulator: isl9305: Add Intersil ISL9305/H driver")
