6.12-stable review patch. If anyone has any objections, please let me know.
From: Kairui Song kasong@tencent.com
commit 74363ec674cb172d8856de25776c8f3103f05e2f upstream.
Setting backing device is done before ZRAM initialization. If we set the backing device, then remove the ZRAM module without initializing the device, the backing device reference will be leaked and the device will be hold forever.
Fix this by always reset the ZRAM fully on rmmod or reset store.
