Subject: Driver-Core: fix devnode callbacks for dabusb and industrialio
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=388dba30471c236a290c4082bce5f2b5cd1a7a06;p=openwrt%2Fstaging%2Fblogic.git

Driver-Core: fix devnode callbacks for dabusb and industrialio

The build of the dabusb driver broke:

  drivers/media/video/dabusb.c:758: error: unknown field 'nodename' specified in initializer
  drivers/media/video/dabusb.c:758: warning: initialization from incompatible pointer type
  make[3]: *** wait: No child processes.  Stop.

Due to this commit:

  e454cea: Driver-Core: extend devnode callbacks to provide permissions

Missing the dabusb driver's dabusb_nodename() callback.

Similar issues with the iio/industrialio driver in staging, pointed out
and patched by Jean Delvare.
