Hi folks,
is there a way to replace obsolete #ifdef's via spatch ?
Here's my scenario:
In the linux kernel we have many places where drivers statically assign
pointers to match tables (eg. for oftree or acpi) into a global driver
struct - sometimes this is enclosed into some #ifdef CONFIG_..., when
things like oftree or acpi are optional.
Example patch for illustrating what I'd like to do:
--- a/sound/soc/codecs/pcm3060-i2c.c
+++ b/sound/soc/codecs/pcm3060-i2c.c
@@ -45,9 +45,7 @@ static int pcm3060_i2c_probe(struct i2c_client *i2c,
static struct i2c_driver pcm3060_i2c_driver = {
.driver = {
.name = "pcm3060",
-#ifdef CONFIG_OF
- .of_match_table = pcm3060_of_match,
-#endif /* CONFIG_OF */
+ .of_match_table = of_match_ptr(pcm3060_of_match),
},
.id_table = pcm3060_i2c_id,
.probe = pcm3060_i2c_probe,
Just wrapping the assignment into the macro call turned out to be easy.
But I haven't found a way to remove the now #ifdef :(
Any idea how I could solve this ?
