Subject[PATCH][next] soc: qcom: fix off-by-one array index bounds check
Date
From: Colin Ian King <colin.king@canonical.com>

The bounds check on model is off-by-one, leading to an array out
of bounds read when model is 26. Fix this.

Addresses-Coverity: ("Out-of-bounds read")
Fixes: e9247e2ce577 ("soc: qcom: socinfo: fix printing of pmic_model")
