From 76dea4cf52784474ca6adc4a2addf55e128b3634 Mon Sep 17 00:00:00 2001 From: William Steidtmann Date: Mon, 15 Apr 2013 17:17:11 -0300 Subject: [PATCH] [media] mceusb: add some missing cmd sizes Fix mceusb_cmdsize() which returns incorrect datasize=0 for sub-commands MCE_RSP_GETPORTSTATUS, MCE_RSP_GETWAKESOURCE, MCE_RSP_EQDEVDETAILS, MCE_RSP_EQEMVER, and MCE_RSP_EQIRNUMPORTS. While here, change mceusb_cmdsize() name to reflect that it returns data size not cmd size.
