Re: [PATCH] Ignore faulty battery on specific touchscreen

[Trent Gamblin <trent@xxxxxxxxxxx>]

Sorry for screwing up the thread first and foremost.

Can anyone comment on this patch or at least give a reason for not 
applying it?

This fixes an annoying low battery popup on a device that seemingly has 
a faulty
battery reporting. I've tested 2 styluses and both do the same (reports 
1% battery
at all times.) Thanks.
