The root dprc is discovered as a platform device in the device tree. The version of that dprc was previously set using hardcoded values from the API header in the kernel). This patch removes the use of the hardcoded version numbers and instead reads the actual dprc version from the hardware. Signed-off-by:

Up until now if the object version expected by a driver (in the API header file) did not match the actual object version in the MC hardware the bus driver refused to bind the object to the driver or printed out WARN_ON dumps. This patch removes those checks, and the responsibility of object version checking should now be done in the object drivers themselves. If the actual version discovered is not supported, the driver's probe function should fail. Drivers should use version checks to support new features and provide backwards compatibility if at all possible. This patch also removes the checks that caused bus driver probing to fail if the overall MC version discovered did not match the firmware version from the API header...this was too strict. The overall MC version is informational like a release number, and continues to be printed in the boot log. Signed-off-by:

The NULL checking here doesn't make sense, so it causes a static checker warning. It turns out that p->mm can't be NULL so the inconsistency is harmless and we should just remove the check. Signed-off-by:

This patch frees memory allocated inside mkimage() in case mkimage() or any other subsequent calls inside prism2_fwapply() from prism2fw.c file fails. To fix this I introduces goto labels where the free operation is done in case some operations fails. After the introduction of goto labels has been done, in order to use the same return path, "return x" instuctions were replaced with "goto" instuctions. Signed-off-by:
