X-Git-Tag: v5.15~5962^2~18
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f58c17c202e7aec9623754a7ec0b0669e043b838;p=platform%2Fkernel%2Flinux-starfive.git

coccinelle: put_device: Add a cast to an expression for an assignment

Extend a when constraint in a SmPL rule so that an additional cast
is optionally excluded from source code searches for an expression
in assignments.
