The goal of this series is to report the firmware version, the bootloader version and the hardware revision of ETAS ES58x devices. These are already reported in the kernel log but this isn't best practice. Remove the kernel log and instead export all these through devlink. In addition, the firmware version is also reported through ethtool. --- * Changelog * v3 -> v4: * major rework to use devlink instead of sysfs following Andrew's comment. * split the series in 6 patches. * [PATCH 1/6] add Acked-by: Greg Kroah-Hartman v2 -> v3: * patch 2/3: do not spam the kernel log anymore with the product number. Instead parse the product information string, extract the firmware version, the bootloadar version and the hardware revision and export them through sysfs. * patch 2/3: rework the parsing in order not to need additional fields in struct es58x_parameters. * patch 3/3: only populate ethtool_drvinfo::fw_version because since commit edaf5df22cb8 ("ethtool: ethtool_get_drvinfo: populate drvinfo fields even if callback exits"), there is no need to populate ethtool_drvinfo::driver and ethtool_drvinfo::bus_info in the driver. v1 -> v2: * was a single patch. It is now a series of three patches. * add a first new patch to export usb_cache_string(). * add a second new patch to apply usb_cache_string() to existing code. * add missing check on product info string to prevent a buffer overflow. * add comma on the last entry of struct es58x_parameters.
