Subject: USB: storage: add quirk for SMI SM3350
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e8497e3b0b7b165d728941eb652bef6eb7684e4a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

USB: storage: add quirk for SMI SM3350

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.
