Subject: hso: fix for the 'invalid frame length' messages
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0de8ca597d7b449e9e7ce7af138944acf06c8f05;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

hso: fix for the 'invalid frame length' messages

Some devices cannot send very short usb transfers. To get around this the
firmware adds a known pattern and flags the driver that it should check for
this pattern on short transfers. This flag was not taken into account by
the driver.
