Subject: [PATCH v12 02/14] dmaengine: idxd: Rename drv_enable/disable_wq to idxd_drv_enable/disable_wq, and export
Rename drv_enable_wq and drv_disable_wq to idxd_drv_enable_wq and
idxd_drv_disable_wq respectively, so that they're no longer too
generic to be exported. This also matches existing naming within the
idxd driver.
And to allow idxd sub-drivers to enable and disable wqs, export them.
