Linux module compilation problem

[Vipul Jain <vipulsj@xxxxxxxxx>]

Hello Everybody,

   I am having issues in compiling my kernel module please help me in this.
   I am attaching my sampledrv.c and Makefile.


   Error I am getting:
   
   make -C /lib/modules/2.6.28-11-generic/build M=/home/vipul/linux/ucsc/ldd modules
