ioctl: Fix wrong return case of get_property
|
|
|
d4b218 |
|
|
|
d4b218 |
If get_property_helper() succeeds in the first time, and then fails in
|
|
|
d4b218 |
the next time, then the ret value will not be updated to an error value.
|
|
|
d4b218 |
This patch removes 'ret' variable to make 'err' to return being updated
|
|
|
d4b218 |
everytime get_property_helper() invoked.
