Which semantic patch did you use here?

The kernel's spatch for this pattern only found and fixed the
following:

 $ make coccicheck COCCI=scripts/coccinelle/api/devm_platform_ioremap_resource.cocci MODE=patch M=drivers/edac | patch -p1
 patching file drivers/edac/ti_edac.c
 patching file drivers/edac/xgene_edac.c
 patching file drivers/edac/synopsys_edac.c

There are probably more drivers to fix than the above and the one you
fixed:

 $ git grep -l platform_get_resource drivers/edac/
 drivers/edac/altera_edac.c
 drivers/edac/armada_xp_edac.c
 drivers/edac/aspeed_edac.c
 drivers/edac/bluefield_edac.c
 drivers/edac/cpc925_edac.c
 drivers/edac/highbank_l2_edac.c
 drivers/edac/highbank_mc_edac.c
 drivers/edac/mv64x60_edac.c
 drivers/edac/synopsys_edac.c
 drivers/edac/ti_edac.c
 drivers/edac/xgene_edac.c

So while at it, how about fixing the .cocci patch in scripts/ and run
it for drivers/edac? There should be one patch only for all edac
drivers.

Thanks,

-Robert
