[PATCH 4.4 37/51] USB: storage: add quirk for SMI SM3350

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Icenowy Zheng <icenowy@xxxxxxx>

commit 0a99cc4b8ee83885ab9f097a3737d1ab28455ac0 upstream.

The SMI SM3350 USB-UFS bridge controller cannot handle long sense request
correctly and will make the chip refuse to do read/write when requested
long sense.

Add a bad sense quirk for it.
