X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=dd1b321e8024fb01404fe163076c9010c5df8608;p=thirdparty%2Fkernel%2Flinux.git

mailbox: imx: use devm_of_platform_populate()

The driver uses of_platform_populate() but does not remove the added
devices on removal. This can lead to "double devices" on module removal
followed by adding the module again.

Use devm_of_platform_populate() to remove the populated devices once the
parent device is removed.
