Subject: fix(bluetooth): include it if Appearance matches the value assigned for keyboard
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8079ceafcac910d0c061830769866710c3e889a8;p=thirdparty%2Fdracut.git

fix(bluetooth): include it if Appearance matches the value assigned for keyboard

Following the Bluetooth spec [1], Assigned Numbers Document, Rev. 2023-05-04,
Section 2.6.3, Appearance Sub-category, the Appearance value defined for
keyboards is 0x03C1.

This value must be checked to include the bluetooth module in hostonly mode,
because some Bluetooth keyboards do not set the Class attribute.
