FYI for compiling compatible drivers for kernel 3.8+

[coreplayer2]

I have come across many issues compiling drivers for kernel 3.8.10 builds.

The first issue "error: implicit declaration of function ‘__devexit_p’ [-Werror=implicit-function-declaration]"
is fixed by removal of all references to __devinit,  __devexit and __devexit_p which are no longer supported in kernel 3.8.x

Along with references to __devexit_p are the parenthesis around the value passed to __devexit_p which need to be removed.
eg: on line with      = __devexit_p (driver remove),
edit to:   =driver remove,

Then the driver will compile (assuming no further issue to be addressed occur).


just an FYI, hope this helps build drivers for 3.8+   unless anyone has a better method?

Next issue I've had references these two functions "kmap_atomic" and "kunmap_atomic"  which apparently no longer accepts two arguments in kernel-3.6 + onward

for example

kmap_atomic(sg->page, KM_IRQ0)
kunmap_atomic(buf, KM_IRQ0)

edited to

kmap_atomic(sg->page)
kunmap_atomic(buf)

compiles and runs without error.   best to allow the driver development team update and test, this works as a temporary measure at least.
