Subject: Incorrect GPIO value with Kernel 3.14.28

Dear all,
I'm currently use Kernel 3.14.28 with release BSP_3.14.28-1.0.1_patch
(on a IMx6 DualLite). When I read the value of a GPIO it give me the bus
value instead of the pin value.
For example when I read GPIO41 it returns me "0" or "512" (the pin is
toggled every seconds), 512 corresponds to the bit 9 (41 - 32) of the bus.
The GPIO value was correct with kernel 3.10.53.
Regards,
Yannick
