Subject: [PATCH v4 01/20] mtd: spi-nor: Use dev_dbg insted of dev_err for low
level info
From: Tudor Ambarus <tudor.ambarus@...rochip.com>
What most users care about is "my dev is not working properly".
All low level information should be discovered when activating
the debug traces.
Keep error messages for just three cases:
- when the JEDEC ID is not recognized
- when the resume() call fails
- when the spi_nor_check() fails.
