TBH, I tend to send out SlimBus and nvmem patches only once around 
rc5-rc6 time which also includes some minor fixes, and you normally 
apply them for next rc1 release.

In this particular case I should have explicitly said to pick them up 
for 5.14 next rc.

Do you want me to resend them with proper cover letter? or are you okay 
to take them as they are?
