This patch series intended to make boot log better. Basically here we just remove unwanted error messages, relying on the message from most deep API to be printed (like mmc subsystem). At the moment this looks like most clean solution to cluttered log problem, as any other solution will be hackish.
With this patch set applied we will see something like this:
Loading Environment from FAT... MMC: no card present Loading Environment from MMC... OK
instead of:
Loading Environment from FAT... MMC: no card present ** Bad device mmc 0 ** Failed (-5) Loading Environment from MMC... OK
Sam Protsenko (2): env: Don't show "Failed" error message disk: part: Don't show redundant error message
