Hi Bjorn,

The following series includes couple of fixes and improvements
associated with the sysfs interfaces. Patches are based on top
of 4.19-rc1. The first 3 patches are independent of each other.

Following is the patch summary:
 - Patch 1 fixes an issue with unbalanced sysfs start/stop
   and module removal
 - Patch 2 adds a minor additional check on firmware name
   being echoed into the sysfs file
 - Patch 3 is a minor kerneldoc fix.
 - Patches 4 and 5 introduce a new request denial to sysfs
   interfaces to not allow userspace to meddle with a remoteproc
   client driven boot flow, and usage of it by Wkup M3 remoteproc
   driver

regards
Suman
