When I try to load cmemk.ko module, it errors saying,
[ 365.654621] CMEMK module: built on Jun 11 2015 at 18:47:18

[ 365.666279] CMEMK Error: Failed to request_mem_region(0x99000000, 0x4000000)
I am not getting the Kernel memory overlap error and I have some memory reserved for dsp cma. This is from my dmesg output,

Any ideas on what is going on? Am I missing something here?
Thanks!
