From 4e168187047bf5d95b66567061007b87c29f7341 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 26 Mar 2020 16:58:06 +0100 Subject: ata: fix CodingStyle issues in PATA timings code * fix the overly long line in ata_timing_quantize() * use standard kernel CodingStyle in ata_timing_merge() * do not use assignment in if condition in ata_timing_compute() * fix non-standard comment style in ata_timing_compute() Reviewed-by: Christoph Hellwig Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Jens Axboe --- drivers/ata/libata-core.c | 42 +++++++++++++++++++++++++++--------------- 1 file changed, 27 insertions(+), 15 deletions(-) (limited to 'drivers/ata') diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index 2ec1a49388ee..acdcedcb3d10 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -3251,7 +3251,8 @@ static const struct ata_timing ata_timing[] = { #define ENOUGH(v, unit) (((v)-1)/(unit)+1) #define EZ(v, unit) ((v)?ENOUGH(((v) * 1000), unit):0) -static void ata_timing_quantize(const struct ata_timing *t, struct ata_timing *q, int T, int UT) +static void ata_timing_quantize(const struct ata_timing *t, + struct ata_timing *q, int T, int UT) { q->setup = EZ(t->setup, T); q->act8b = EZ(t->act8b, T); @@ -3267,15 +3268,24 @@ static void ata_timing_quantize(const struct ata_timing *t, struct ata_timing *q void ata_timing_merge(const struct ata_timing *a, const struct ata_timing *b, struct ata_timing *m, unsigned int what) { - if (what & ATA_TIMING_SETUP ) m->setup = max(a->setup, b->setup); - if (what & ATA_TIMING_ACT8B ) m->act8b = max(a->act8b, b->act8b); - if (what & ATA_TIMING_REC8B ) m->rec8b = max(a->rec8b, b->rec8b); - if (what & ATA_TIMING_CYC8B ) m->cyc8b = max(a->cyc8b, b->cyc8b); - if (what & ATA_TIMING_ACTIVE ) m->active = max(a->active, b->active); - if (what & ATA_TIMING_RECOVER) m->recover = max(a->recover, b->recover); - if (what & ATA_TIMING_DMACK_HOLD) m->dmack_hold = max(a->dmack_hold, b->dmack_hold); - if (what & ATA_TIMING_CYCLE ) m->cycle = max(a->cycle, b->cycle); - if (what & ATA_TIMING_UDMA ) m->udma = max(a->udma, b->udma); + if (what & ATA_TIMING_SETUP) + m->setup = max(a->setup, b->setup); + if (what & ATA_TIMING_ACT8B) + m->act8b = max(a->act8b, b->act8b); + if (what & ATA_TIMING_REC8B) + m->rec8b = max(a->rec8b, b->rec8b); + if (what & ATA_TIMING_CYC8B) + m->cyc8b = max(a->cyc8b, b->cyc8b); + if (what & ATA_TIMING_ACTIVE) + m->active = max(a->active, b->active); + if (what & ATA_TIMING_RECOVER) + m->recover = max(a->recover, b->recover); + if (what & ATA_TIMING_DMACK_HOLD) + m->dmack_hold = max(a->dmack_hold, b->dmack_hold); + if (what & ATA_TIMING_CYCLE) + m->cycle = max(a->cycle, b->cycle); + if (what & ATA_TIMING_UDMA) + m->udma = max(a->udma, b->udma); } EXPORT_SYMBOL_GPL(ata_timing_merge); @@ -3306,8 +3316,8 @@ int ata_timing_compute(struct ata_device *adev, unsigned short speed, /* * Find the mode. */ - - if (!(s = ata_timing_find_mode(speed))) + s = ata_timing_find_mode(speed); + if (!s) return -EINVAL; memcpy(t, s, sizeof(*s)); @@ -3363,9 +3373,11 @@ int ata_timing_compute(struct ata_device *adev, unsigned short speed, t->recover = t->cycle - t->active; } - /* In a few cases quantisation may produce enough errors to - leave t->cycle too low for the sum of active and recovery - if so we must correct this */ + /* + * In a few cases quantisation may produce enough errors to + * leave t->cycle too low for the sum of active and recovery + * if so we must correct this. + */ if (t->active + t->recover > t->cycle) t->cycle = t->active + t->recover; -- cgit 1.4.1
