Subject: [PATCH 1/1] powerpc-utils: Suppress errors reading kernel
|
|
files
|
|
|
|
A problem was observed with the evaluation of the '${devspec}'
|
|
by the script 'ofpathname'. This patch provided improved
|
|
handling of errors within that script, and by some of the
|
|
follow-on uses of the tool by the 'bootlist' script.
|
|
|
|
* Deal with error messages returned sometimes by evaluation
|
|
of ${devspec} in 'ofpathname'.
|
|
* Strip embedded nulls from values provided by kernel files,
|
|
especially, /proc/device-tree${devspec}/namespace/name,
|
|
in 'ofpathname'.
|
|
* Redirect more error messages to /dev/null
|
|
