From 02745f63443c08b9b82ab2d654a0f5fc3699e586 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 26 Mar 2013 04:45:11 -0300 Subject: [PATCH] [media] go7007: fix invalid use of sizeof in go7007_usb_i2c_master_xfer() sizeof() when applied to a pointer typed expression gives the size of the pointer, not that of the pointed data.
