Subject: USB: yurex: Fix missing URB_NO_TRANSFER_DMA_MAP flag in urb
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=532f17b5d59bf0deb6f1ff9bc1fb27d5b5011c09;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

USB: yurex: Fix missing URB_NO_TRANSFER_DMA_MAP flag in urb

Current probing code is setting URB_NO_TRANSFER_DMA_MAP flag into a wrong urb
structure, and this causes BUG_ON with some USB host implementations.
This patch fixes the issue.
