From 9726ba4abaa16cd6c385ad350d403f98a8eacf52 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 27 Mar 2009 16:34:21 -0400 Subject: [PATCH] sf: stmicro: drop redundant id read The common SPI flash code reads the idcode and passes it down to the SPI flash driver, so there is no need to read it again ourselves.
