regulator: isl9305: fix array size

vstehle · broonie · commit 0c08aaf87317 · 2017-04-10T17:31:17.000+01:00
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: dec38b5 ("regulator: isl9305: Add Intersil ISL9305/H driver") Signed-off-by: Vincent Stehlé <vincent.stehle@laposte.net> Cc: Mark Brown <broonie@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
