Subject: checkpatch: values: double ampersand may be unary
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0d413866c7df63794790518e3fd5890969c206ad;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

checkpatch: values: double ampersand may be unary

It is possible to use double ampersand (&&) in unary context where it
means the address of a goto label.  Handle spacing for it.
