Can a blank line be omitted between the message and the error code?

I got the impression that the resource management is still questionable
for this function implementation.
1. Now I suggest to move the call of the function “brelse” to the end
of the while loop. The label “release_bh” would be renamed to “free_table” then.
2. Can a variable initialisation be converted to the assignment “ret = -EIO;”
in an if branch?

Markus
