Subject: printk: reduce setup_text_buf size to LOG_LINE_MAX
X-Git-Tag: v5.10.7~1457^2^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0463d04ea03a12d8a5aad42197a5945dfd78d7d6;p=platform%2Fkernel%2Flinux-rpi.git

printk: reduce setup_text_buf size to LOG_LINE_MAX

@setup_text_buf only copies the original text messages (without any
prefix or extended text). It only needs to be LOG_LINE_MAX in size.
