Subject: Bluetooth: Remove unused h4_check_data_len() function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8909f6d2c450d0a878bcb1d1184ed0114c5724c9;p=linux-beck.git

Bluetooth: Remove unused h4_check_data_len() function

The function h4_check_data_len() is actually not used. So just
remove it.
