Subject: [PATCH v1 1/5] power: return -ENOMEM on OCV table alloc failure
Date: Mon, 31 Aug 2026 12:53:35 -0300 [thread overview]
Message-ID: <20260831155339.181487-2-ivanrwcm25@gmail.com> (raw)
In-Reply-To: <20260831155339.181487-1-ivanrwcm25@gmail.com>
power_supply_get_battery_info() maps a failed kcalloc() for the OCV
capacity table to -EINVAL. Return -ENOMEM instead, matching the
resistance-temp-table allocation path in the same function.
