Re: [PATCH] mtd: spi-nor: stop printing superfluous debug info

From: Michael Walle

Hi,

The mtd data can be obtain with the mtd ioctls and the SPI NOR
flash name can be determined interrogating the sysfs entries.
Stop polluting the kernel log.

I'd lower this to dev_dbg() and print the jedec id. It might come in
handy for a quick glance during bootup if debug is enabled.

-
- dev_dbg(dev,
- "mtd .name = %s, .size = 0x%llx (%lldMiB), "
- ".erasesize = 0x%.8x (%uKiB) .numeraseregions = %d\n",
- mtd->name, (long long)mtd->size, (long long)(mtd->size >> 20),
- mtd->erasesize, mtd->erasesize / 1024, mtd->numeraseregions);
-
- if (mtd->numeraseregions)
- for (i = 0; i < mtd->numeraseregions; i++)
- dev_dbg(dev,
- "mtd.eraseregions[%d] = { .offset = 0x%llx, "
- ".erasesize = 0x%.8x (%uKiB), "
- ".numblocks = %d }\n",
- i, (long long)mtd->eraseregions[i].offset,
- mtd->eraseregions[i].erasesize,
- mtd->eraseregions[i].erasesize / 1024,
- mtd->eraseregions[i].numblocks);
return 0;

Part of this is already available through the spi-nor debugfs, although not
the actual mtd properties. These I think, should go into the mtdcore
itself if really needed. Either through dev_dbg() or debugfs.
