Subject: [PATCH AUTOSEL 4.14 08/21] ieee802154: ca8210: prevent memory leak
Date: Wed,  9 Oct 2019 13:06:01 -0400	[thread overview]
Message-ID: <20191009170615.32750-8-sashal@kernel.org> (raw)
In-Reply-To: <20191009170615.32750-1-sashal@kernel.org>

From: Navid Emamdoost <navid.emamdoost@gmail.com>

[ Upstream commit 6402939ec86eaf226c8b8ae00ed983936b164908 ]

In ca8210_probe the allocated pdata needs to be assigned to
spi_device->dev.platform_data before calling ca8210_get_platform_data.
Othrwise when ca8210_get_platform_data fails pdata cannot be released.
