no branch 问题

现象如下：

lynn.feng:~/project/Git/M_MT6737_MP$ git branch -a
* (no branch)
a36_panasonic_l004
b36_panasonic_tmp
master

 

lynn.feng:~/project/Git/M_MT6737_MP$ git checkout master
kernel-3.18/drivers/input/touchscreen/mediatek/GT9XX_B36/gt9xx_driver.c: needs merge
error: you need to resolve your current index first

 

lynn.feng:~/project/Git/M_MT6737_MP$ git status
# Not currently on any branch.

 

该问题已经说的很明白了，有文件没有提交，所以git树无法统一，解决方法如下：

git reset --merge
