From 0d9032477f4ba2323079466efef0c1419613eebf Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 3 Jan 2012 03:46:47 +0000 Subject: net: fsl: fec: fix build for mx23-only kernel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If one only selects mx23-based boards, compile fails: drivers/net/ethernet/freescale/fec.c:410:2: error: 'FEC_HASH_TABLE_HIGH' undeclared (first use in this function) drivers/net/ethernet/freescale/fec.c:411:2: error: 'FEC_HASH_TABLE_LOW' undeclared (first use in this function) This is because fec.h uses CONFIG_SOC_IMX28 to determine the register layout of the core which makes sense since the MX23 does not have a fec. However, Kconfig uses the broader ARCH_MXS symbol and this way even makes the fec-driver default for MX23. Adapt Kconfig to use the more precise SOC_IMX28 as well.

In this case cmd wait queue handler gets called with no command in queue (i.e. adapter->cmd_queued = NULL).
