I think you're correct but you missed other occurrences of this function call:
$ grep platform_set_drvdata *.c bytcht_da7213.c: platform_set_drvdata(pdev, card); bytcht_es8316.c: platform_set_drvdata(pdev, &byt_cht_es8316_card); bytcht_nocodec.c: platform_set_drvdata(pdev, &bytcht_nocodec_card); bytcr_rt5640.c: platform_set_drvdata(pdev, &byt_rt5640_card); bytcr_rt5651.c: platform_set_drvdata(pdev, &byt_rt5651_card); cht_bsw_max98090_ti.c: platform_set_drvdata(pdev, &snd_soc_card_cht); cht_bsw_rt5645.c: platform_set_drvdata(pdev, card); cht_bsw_rt5672.c: platform_set_drvdata(pdev, &snd_soc_card_cht); mfld_machine.c: platform_set_drvdata(pdev, mc_drv_ctx);
