Subject: [PATCH] ieee802154: ca8210: prevent memory leak
Date: Tue, 17 Sep 2019 17:47:12 -0500 [thread overview]
Message-ID: <20190917224713.26371-1-navid.emamdoost@gmail.com> (raw)
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.
