Merge patch series "can: remove litteral strings used for driver names and remove DRV_VERSION"

Vincent Mailhol <mailhol.vincent@wanadoo.fr> says:

====================

This is a cleanup series.

The patches 1 to 8 get rid of any hardcoded strings and instead relies
on the KBUILD_MODNAME macros to get the device name. Patch 9 replaces
the ES58X_MODULE_NAME macro with KBUILD_MODNAME in
etas_es58x. Finally, also in etas_es58x, patch 10 removes the
DRV_VERSION so that the module uses the default behavior and advertise
the kernel version instead of a custom version.

* Changelog *

v1 -> v2:

  * The patch for esd_usb contained some changes for ems_usb.

  * v1 assumed that KBUILD_MODNAME could only be used when the file
    basename and the module had the same name (e.g. vcan.c for the
    vcan.ko). The fact is that KBUILD_NAME extends to the module name
    and can thus be used even if the basename is different
    (e.g. slcan-core.c and slcan.ko)

  * Add patch #9: can: etas_es58x: replace ES58X_MODULE_NAME with
    KBUILD_MODNAME

v1: https://lore.kernel.org/all/20220725153124.467061-1-mailhol.vincent@wanadoo.fr

This series are the first 9 patches of:
https://lore.kernel.org/linux-can/20220725133208.432176-1-mailhol.vincent@wanadoo.fr/T/

The initial intent of those 9 patches was to do so cleanup in order to
implement ethtool_ops::get_drvinfo but this appeared to be useless:
https://lore.kernel.org/linux-can/20220725140911.2djwxfrx3kdmjeuc@pengutronix.de/

Instead, those patch are send as a standalone series.

====================

Drop "[PATCH v2 03/10] can: slcan: use KBUILD_MODNAME and define
pr_fmt to replace hardcoded names" to avoid conflicts with Dario
Binacchi's work on the slcan driver.
