Print the string for which conversion failed instead of printing the
function name twice.

Hi Martin,
With CONFIG_DYNAMIC_DEBUG=y, the output of pr_debug() statements is
controlled by the settings in /sys/kernel/debug/dynamic_debug/control.
From Documentation/admin-guide/dynamic-debug-howto.rst:
p enables the pr_debug() callsite.
f Include the function name in the printed message
l Include line number in the printed message
m Include module name in the printed message
t Include thread ID in messages not generated from interrupt context
_ No flags are set. (Or'd with others on input)
In other words, the dynamic debug infrastructure already supports
printing the function name. I use the pmf flags when enabling pr_debug()
statements. This is why I wrote that explicitly printing the function
name causes the function name to be printed twice.
Please let me know if you need more information.
Bart.

OK.
Applied to 5.5/scsi-queue, thanks.
