From 891e0559387e94292287f5c5d1c61cd39742f46b Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Mon, 5 Oct 2015 21:16:39 -0300 Subject: [PATCH] [media] rtl2832: print reg number on error case It is hard to debug possible I2C failures without knowing the possible register itself. Add register number to error printing.
