编译内核文件时候,报如下错误信息:

WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
  CC      /mnt/hgfs/share/work/lcmxo2-2000hc/cpld_lcmxo2-2000hc.mod.o
  LD [M]  /mnt/hgfs/share/work/lcmxo2-2000hc/cpld_lcmxo2-2000hc.ko
make[2]: warning:  Clock skew detected.  Your build may be incomplete.
make[1]: Leaving directory `/home/thy/ltib/rpm/BUILD/linux-2.6.35.3'

解决办法:
执行:
$ make CONFIG_DEBUG_SECTION_MISMATCH=y
会出现错误的详细信息:

黄色背景字体为问题所在,去掉"__init",将
static int  __init mx28_cpld_probe(struct spi_device *spi)
改为:
static int  mx28_cpld_probe(struct spi_device *spi)

问题解决
