Subject: Input: wacom - add serial number for Graphire4 and old Bamboo
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=998c454e1c850f8e5cc0ae2299c4789b395d6d98;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Input: wacom - add serial number for Graphire4 and old Bamboo

With the removal of BTN_TOOL_FINGER for tablet buttons and
expresskeys, serial number is needed to distingush if the
events were from a regular tool (stylus, eraser, or mouse)
or the attribures (buttons, strips, or wheels) on the tablet
since there are overlapped events between the tools and the
tablet attributes.
