try removing __devinit and __devexit from probe and remove. This is not needed as it is module.

Hi,
I am facing the following error when i am building the kernel.
ERROR: modpost: Found 2 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
To build the kernel despite the mismatches, build with:
'make CONFIG_NO_ERROR_ON_MISMATCH=y'
(NOTE: This is not recommended)
make[3]: *** [__modpost] Error 1
make[2]: *** [modules] Error 2
make[1]: *** [sub-make] Error 2
After i did make the kernel using make CONFIG_DEBUG_SECTION_MISMATCH=y it said section mismatch .I am trying to write a platform driver (not sure if my code is right )

module_exit(mymodule_exit);Can anybody throw some light on what might be happening here ?
