X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bee91869436dfb0e444139a52228cef0ce758cd8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

usb: gadget: f_mass_storage: Fix the logic to iterate all common->luns

It is wrong to do --i in the for loop.

Fixes: dd02ea5a3305 ("usb: gadget: mass_storage: Use static array for luns")
