1e9dea2a60
This patch makes it possible to use the Coccinelle checker with the C
variable of the build system. To check only newly edited code, the
following command may be used:
'make C={1,2} CHECK="scripts/coccicheck"'
This runs every semantic patch in scripts/coccinelle by default. The
COCCI variable may additionally be used to only apply a single
semantic patch.
