[sos-devel] [PATCH] [powerpc] Read msglog file, instead of copying it

[Kamalesh Babulal]

/sys/firmware/opal/msglog file is a read interface to
capture OPAL ring buffer. Copying msglog file, will
result in file being ignored as size of the file will
be zero always.

Fix this issue by removing the file from list of files
to be copied and read the file to capture the ring buffer
as command output.
