Browse Source 
Below MISRA 10.1 violation is reported in nvgpu.common.mm.as

${TEGRA_TOP}/kernel/nvgpu/drivers/gpu/nvgpu/common/mm/as.c:69:
misra_violation: The expression "({...})" of non-boolean essential
type is being interpreted as a boolean value for the operator "!".

Fix this by adding an explicit cast to bool in is_power_of_2
macro.
