changes to a core file : Should all associated drivers be rebuilt as [M]

changes to a core file : Should all associated drivers be rebuilt as [M]

Hello,
If we make a change to a core file that appear to be common across more 
than one driver(s), should we be reconfiguring the kernel build to set all 
drivers as [M]?

Also, is this a correct change to the .config file:

from : # CONFIG_FB_TFT is not set
to     : CONFIG_FB_TFT=m


Thank you,
Deepak.

You can use

make allyesconfig

Always be sure that the file you changed actually has a .o file after
compiling.
