+Subject: [PATCH 061/102] net: mediatek: check device_reset return code
+
+The device_reset() function may fail, so we have to check
+its return value, e.g. to make deferred probing work correctly.
+gcc warns about it because of the warn_unused_result attribute:
+
+drivers/net/ethernet/mediatek/mtk_eth_soc.c: In function 'mtk_probe':
+drivers/net/ethernet/mediatek/mtk_eth_soc.c:1679:2: error: ignoring return value of 'device_reset', declared with attribute warn_unused_result [-Werror=unused-result]
+
+This adds the trivial error check to propagate the return value
+to the generic platform device probe code.
+
