Hello John Crispin,
The patch 8b634a9c7620: "staging: mt7621-mmc: MIPS: ralink: add sdhci
for mt7620a SoC" from Mar 15, 2018, leads to the following static
checker warning:
drivers/staging/mt7621-mmc/sd.c:2790 msdc_drv_probe()
warn: curly braces intended?
drivers/staging/mt7621-mmc/sd.c
2777 /* For sd card: MSDC_SYS_SUSPEND | MSDC_WP_PIN_EN | MSDC_CD_PIN_EN | MSDC_REMOVABLE | MSDC_HIGHSPEED,
2778 For sdio : MSDC_EXT_SDIO_IRQ | MSDC_HIGHSPEED */
2779 if (hw->flags & MSDC_HIGHSPEED) {
2780 mmc->caps = MMC_CAP_MMC_HIGHSPEED | MMC_CAP_SD_HIGHSPEED;
2781 }
2782 if (hw->data_pins == 4) { /* current data_pins are all 4*/
2783 mmc->caps |= MMC_CAP_4_BIT_DATA;
2784 } else if (hw->data_pins == 8) {
2785 mmc->caps |= MMC_CAP_8_BIT_DATA;
2786 }
2787 if ((hw->flags & MSDC_SDIO_IRQ) || (hw->flags & MSDC_EXT_SDIO_IRQ))
Are curly braces intended for this if statement?
2788 mmc->caps |= MMC_CAP_SDIO_IRQ; /* yes for sdio */
2789
2790 cd_active_low = !of_property_read_bool(pdev->dev.of_node, "mediatek,cd-high");
2791 mtk_sw_poll = of_property_read_bool(pdev->dev.of_node, "mediatek,cd-poll");
2792
2793 if (mtk_sw_poll)
2794 mmc->caps |= MMC_CAP_NEEDS_POLL;
because the indenting seems to say that the braces should reach up to
here.
2795
2796 /* MMC core transfer sizes tunable parameters */
2797 #if LINUX_VERSION_CODE > KERNEL_VERSION(3,10,0)
2798 mmc->max_segs = MAX_HW_SGMTS;
2799 #else
2800 mmc->max_hw_segs = MAX_HW_SGMTS;
2801 mmc->max_phys_segs = MAX_PHY_SGMTS;
2802 #endif
