bitops: Add missing parentheses to new get_order macro
The new get_order macro introcuded in commit d66acc39c7cee323733c8503b9de1821a56dff7e does not use parentheses around all uses of the parameter n. This causes new compile warnings, for example in the amd_iommu_init.c function: drivers/iommu/amd_iommu_init.c:561:6: warning: suggest parentheses around comparison in operand of ‘&’ [-Wparentheses] drivers/iommu/amd_iommu_init.c:561:6: warning: suggest parentheses around comparison in operand of ‘&’ [-Wparentheses] Fix those warnings by adding the missing parentheses.
