From: Oliver Neukum Date: Mon, 6 Jul 2015 11:12:32 +0000 (+0200) Subject: usb-storage: ignore ZTE MF 823 card reader in mode 0x1225 X-Git-Tag: v3.18.21~50 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cf584dd3d8b82bfc3a961827259e857c58d831f3;p=thirdparty%2Fkernel%2Fstable.git usb-storage: ignore ZTE MF 823 card reader in mode 0x1225 [ Upstream commit 5fb2c782f451a4fb9c19c076e2c442839faf0f76 ] This device automatically switches itself to another mode (0x1405) unless the specific access pattern of Windows is followed in its initial mode. That makes a dirty unmount of the internal storage devices inevitable if they are mounted. So the card reader of such a device should be ignored, lest an unclean removal become inevitable. This replaces an earlier patch that ignored all LUNs of this device. That patch was overly broad.
