From: Siddharth Vadapalli <[email protected]>Commit f3f11cfe8907 ("remoteproc: k3-r5: Acquire mailbox handle during probe routine") introduced a check in the "k3_r5_rproc_mbox_callback()" and "k3_r5_rproc_kick()" callbacks, causing them to exit if the remote core's state is "RPROC_DETACHED". However, the "__rproc_attach()" function that is responsible for attaching to a remote core, updates the state of the remote core to "RPROC_ATTACHED" only after invoking "rproc_start_subdevices()". The "rproc_start_subdevices()" function triggers the probe of the Virtio RPMsg devices associated with the remote core, which require that the "k3_r5_rproc_kick()" and "k3_r5_rproc_mbox_callback()" callbacks are functional. Hence, drop the check in the callbacks.

This patch seems out of place here, while you do need to do this before the next couple patches, this patch stands alone and probably should go at the start of the series before the start of the refactoring. Andrew
