Subject: [PATCH] s390x/sclp: Simplify get_sclp_device() cheery-pick from
|
||
|
|
3d9836e46dbe1e46c39fe76a62d3085a71ddbf7a get_sclp_device() scans the whole
|
||
|
|
machine to find a TYPE_SCLP object. Now that the SCLPDevice instance is
|
||
|
|
available under the machine state, use it to simplify the lookup. While at
|
||
|
|
it, remove the inline to let the compiler decide on how to optimize.
