printk: buffer overflow fixes

Hello stable,

The following printk patches fixing a buffer overflow potential in 5.10 are now available in Linus' tree:

f0e386ee0c0b71ea6f7238506a4d0965a2dbef11 ("printk: fix buffer overflow potential for print_text()")

08d60e5999540110576e7c1346d486220751b7f9 ("printk: fix string termination for record_print_text()")

The first one (f0e386ee0c0b) was already queued up for 5.10-stable but I requested it not be applied until this second one was accepted. Now they are both accepted and both should be applied. Thanks.

John Ogness
