Subject: [PATCH 134/195] printk: Add @flags argument for console_is_usable()
|
|
|
|
The caller of console_is_usable() usually needs @console->flags
|
|
for its own checks. Rather than having console_is_usable() read
|
|
its own copy, make the caller pass in the @flags. This also
|
|
ensures that the caller saw the same @flags value.
