Hi
I am writing a keypad module (device driver for linux input subsystem) for
STs Nomadik platform based on arm arch.
My problem is-
I have used input_allocate_device() in mdule init function
if I use kfree() in module exit function to free used memory by
module. Module gives page fault durring next insmod operation. why is
it so?
If I dont free the memory in exit function module works fine for
sucessive insmod/rmmod operations but leads to memory leak as we know
we are not freeing it
Show the code.
What is problem? how to solve it?
No idea without seeing the code.
