kbuild: prevent modpost from looking for a .cmd file for a static library linked into a module
This fixes a compile time warning which occurs whenever a static library is linked into a kernel module. MODPOST tries to look for a ".<modulename>.cmd" file to look for its dependencies, but that file doesn't exist or get generated for static libraries. This patch prevents modpost from looking for a .cmd file when a module is linked with a static library [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Ashutosh Naik <ashutosh.naik@gmail.com> Cc: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
