Fix some "bigger" issues reported by checkpatch.pl: - Block comments use * on subsequent lines - Blank lines aren't necessary before a close brace - Block comments use a trailing */ on a separate line - Alignment should match open parenthesis - void function return statements are not generally useful - char * array declaration might be better as static const - printk() should include KERN_<LEVEL> facility level: replace printk() with pr_debug() to include facility level - Some spelling mistakes Signed-off-by: Jona Crasselt <jona.crasselt@xxxxxx> Signed-off-by: Felix Windsheimer <felix.windsheimer@xxxxxx> --- drivers/staging/mt7621-mmc/sd.c | 62 ++++++++++++++++----------------- 1 file changed, 31 insertions(+), 31 deletions(-) diff --git a/drivers/staging/mt7621-mmc/sd.c b/drivers/staging/mt7621-mmc/sd.c index 7b66f9b0a094..e137ce2c9f44 100644 --- a/drivers/staging/mt7621-mmc/sd.c +++ b/drivers/staging/mt7621-mmc/sd.c @@ -78,7 +78,8 @@ #define CMD_TIMEOUT (HZ / 10) /* 100ms */ #define DAT_TIMEOUT (HZ / 2 * 5) /* 500ms x5 */ -#define MAX_DMA_CNT (64 * 1024 - 512) /* a single transaction for WIFI may be 50K*/ +/* a single transaction for WIFI may be 50K*/ +#define MAX_DMA_CNT (64 * 1024 - 512) #define MAX_GPD_NUM (1 + 1) /* one null gpd */ #define MAX_BD_NUM (1024) @@ -318,9 +319,9 @@ static void msdc_abort_data(struct msdc_host *host) #ifdef CONFIG_PM /* - register as callback function of WIFI(combo_sdio_register_pm) . - can called by msdc_drv_suspend/resume too. -*/ + * register as callback function of WIFI(combo_sdio_register_pm) . + * can called by msdc_drv_suspend/resume too. + */ static void msdc_pm(pm_message_t state, void *data) { struct msdc_host *host = (struct msdc_host *)data; @@ -351,7 +352,6 @@ static void msdc_pm(pm_message_t state, void *data) host->suspend = 0; host->pm_state = state; - } } #endif @@ -685,7 +685,7 @@ static int msdc_do_request(struct mmc_host *mmc, struct mmc_request *mrq) if (read) { if ((host->timeout_ns != data->timeout_ns) || - (host->timeout_clks != data->timeout_clks)) { + (host->timeout_clks != data->timeout_clks)) { msdc_set_timeout(host, data->timeout_ns, data->timeout_clks); } } @@ -711,7 +711,8 @@ static int msdc_do_request(struct mmc_host *mmc, struct mmc_request *mrq) goto done; /* for read, the data coming too fast, then CRC error - start DMA no business with CRC. */ + * start DMA no business with CRC. + */ //init_completion(&host->xfer_done); msdc_dma_start(host); @@ -794,9 +795,10 @@ static int msdc_tune_cmdrsp(struct msdc_host *host, struct mmc_command *cmd) u32 skip = 1; /* ==== don't support 3.0 now ==== - 1: R_SMPL[1] - 2: PAD_CMD_RESP_RXDLY[26:22] - ==========================*/ + * 1: R_SMPL[1] + * 2: PAD_CMD_RESP_RXDLY[26:22] + * ========================== + */ // save the previous tune result sdr_get_field(host->base + MSDC_IOCON, MSDC_IOCON_RSPL, &orig_rsmpl); @@ -1188,8 +1190,6 @@ static void msdc_ops_request(struct mmc_host *mmc, struct mmc_request *mrq) spin_unlock(&host->lock); mmc_request_done(mmc, mrq); - - return; } /* called by ops.set_ios */ @@ -1223,26 +1223,26 @@ static void msdc_ops_set_ios(struct mmc_host *mmc, struct mmc_ios *ios) u32 ddr = 0; #ifdef MT6575_SD_DEBUG - static char *vdd[] = { + static const char * const vdd[] = { "1.50v", "1.55v", "1.60v", "1.65v", "1.70v", "1.80v", "1.90v", "2.00v", "2.10v", "2.20v", "2.30v", "2.40v", "2.50v", "2.60v", "2.70v", "2.80v", "2.90v", "3.00v", "3.10v", "3.20v", "3.30v", "3.40v", "3.50v", "3.60v" }; - static char *power_mode[] = { + static const char * const power_mode[] = { "OFF", "UP", "ON" }; - static char *bus_mode[] = { + static const char * const bus_mode[] = { "UNKNOWN", "OPENDRAIN", "PUSHPULL" }; - static char *timing[] = { + static const char * const timing[] = { "LEGACY", "MMC_HS", "SD_HS" }; - printk("SET_IOS: CLK(%dkHz), BUS(%s), BW(%u), PWR(%s), VDD(%s), TIMING(%s)", - ios->clock / 1000, bus_mode[ios->bus_mode], - (ios->bus_width == MMC_BUS_WIDTH_4) ?
