Even if we fix those two, we still have some more printk strings
that start with a lower case.


line 177:  dev_err(denali->dev, "reset bank failed.\n");

line 699:  pr_err("timeout occurred, status = 0x%x, mask = 0x%x\n",

line 863:  dev_err(denali->dev, "unable to send pipeline command\n");

line 1074:  dev_err(denali->dev, "timeout on write_page (type = %d)\n",

line 1309:  pr_err(": unsupported command received 0x%x\n", cmd);



If you say "consistency's sake" and
you are a big fan of capital letters instead of lower cases,
will you send a patch that touches those globally?


Your comments against this series are just about
"upper cases vs lower cases".

If I get more useful comments, I am happy to send v2.

But, at this moment, I see no good reason for v2
because changing those two lines does not give us any consistency.
