I suppose I should have acked the radeonfb one... I'm a bit of a slacker
with radeonfb maintainership lately.
However, in this case, I think I'll NACK it. I don't think it's fair to
fail the fb initialization because it couldn't create the EDID files. A
warning in dmesg is enough. For lots of machines, failing the fb init
means no console at all...
In general, I share paulus point of view here that forcing us to test
all those result code from sysfs file creation functions is just a major
PITA and adds bloat all over the kernel. There are many many cases where
the "obvious" thing of erroring out is actually not good policy. In many
cases, the failure to create some random sysfs file shouldn't prevent
the driver from operating, because the consequences of doing the later
are worse than the consequences of not having that sysfs file in the
first place. Thus, warnings are a better thing to do. But multiply the
number of sysfs_* calls by the code size of adding a test & printk and
you'll get the direct non-configurable-out bloat to the kernel.
