Subject: mtip32xx: use BLK_STS_DEV_RESOURCE for device resources
X-Git-Tag: v5.0-rc1~52^2~97
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=4ba09f69e20d0a768d91277847ddbd31f476590e;p=linux.git

mtip32xx: use BLK_STS_DEV_RESOURCE for device resources

For cases where we can only fail with IO in-flight, we should be using
BLK_STS_DEV_RESOURCE instead of BLK_STS_RESOURCE. The latter refers to
system wide resource constraints.
