Subject: USB: cp210x: increase bulk-in buffer size to 256 byte
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aea006b93a59864473866e4b1bdb51deea593798;p=linux-beck.git

USB: cp210x: increase bulk-in buffer size to 256 byte

The cp210x requires a bulk-in buffer larger than endpoint size to keep
up at high baudrates without loosing data.
