Hi Krishna,
Coding a kernel module is not like coding a user-mode program. You
should never write a module that requires reading or writing to any
logical device. The kernel is the thing that translates physical
I/O to logical I/O. Attempting to perform logical I/O in the kernel
is effectively going backwards.
The kernel is not a process. A file-descriptor needs a process-context
for it to mean anything. Otherwise how would the kernel keep your
STDIN_FILENO separate from somebody else's STDIN_FILENO?
However if you want to open a file for writing please refer this example

Regards,
Jayant.
