Subject: ieee802154: ca8210: prevent memory leak
Git-commit: 6402939ec86eaf226c8b8ae00ed983936b164908
Patch-mainline: 5.4-rc2
References: CVE-2019-19075 bsc#1157162 bnc#1151927 5.3.8

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.
