From 57157becdd1d23e6c2b8661ffe6c78d7d605d121 Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Tue, 31 Aug 2010 17:27:02 -0700 Subject: [PATCH] Input: bcm5974 - adjust major/minor to scale By visual inspection, the reported touch_major and touch_minor axes are a factor of two too small. Presumably the device actually reports the semi-major and semi-minor axes. Corrected with this patch.
