Subject: fs/proc: remove redundant comments from /proc/bootconfig
From: Zhenhua Huang <quic_zhenhuah@xxxxxxxxxxx>
commit fbbdc255fbee59b4207a5398fdb4f04590681a79 upstream.
commit 717c7c894d4b ("fs/proc: Add boot loader arguments as comment to
/proc/bootconfig") adds bootloader argument comments into /proc/bootconfig.
/proc/bootconfig shows boot_command_line[] multiple times following
every xbc key value pair, that's duplicated and not necessary.
Remove redundant ones.
Output before and after the fix is like:
key1 = value1
*bootloader argument comments*
key2 = value2
*bootloader argument comments*
key3 = value3
*bootloader argument comments*
..
key1 = value1
key2 = value2
key3 = value3
*bootloader argument comments*
..
