| |
Hi,
I have noticed that sparse generates a lot of "ignoring return value of 'device_create_file'" warnings.
(cat sparse.txt | grep -c "device_create_file" 1231 :)
I want to fix this warnings, but I'm wondering how to properly handle return value of device_create_file function.
The shortest way.
int foo() { int error;
[..]
error = device_create_file(&bar, &bas)
if (error) return error; }
A bit longer way.
int foo() { int error;
[..]
error = device_create_file(&bar, &bas)
if (error) { subsystem_remove_device(bar); return error; } }
Any hints?
Regards, Michal
