Subject: [PATCH] power_supply: 88pm860x_charger: do not pass NULL to power_supply_put
Date: Sun, 28 Feb 2016 19:57:58 +0000 [thread overview]
Message-ID: <1456689478-7318-1-git-send-email-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
In the case where power_supply_get_by_name returns NULL the current
error return path calls power_supply_put with a NULL psy which will
cause a null pointer dereference. Avoid this with an immediate
return.
