The problem triggers from the command around line 39:

This statement fails when 'comm' is not in $PATH, creating an empty

will always be false since the file is empty, and the script will exit
successfully as if everything were OK.

The case where 'comm' in not in $PATH is not theoretical. It used to
happen on yocto until a recent fix [0], and still happens on the
current stable branch (rocko).

Fix by setting the errexit flag to exit with error when a statement

commit 1601dd97edc6 ("davinci: omapl138_lcdk: increase PLL0 frequency")
changed the PLL0 frequency to 456MHz, which is needed for the LCDC IP
block. However, in doing so, it caused the PLLOUT clock to be outside
of the allowable specifications given in the OMAP-L138 data sheet. (It
says PLLOUT must be 600MHz max). It also uses a PLLM value outside of
the range given in the TRM (it says PLLM must in the range 0 to 0x1f).

So here is what we have currently:

PLLOUT = 24 / (0 + 1) * (37 + 1) = 912MHz (out of spec)
         ^     ^         ^

                    ^     ^
                 PLLOUT POSTDIV

This changes the PLLM value to 18 and the POSTDIV value to 0 so that
PLLOUT is now within specification but we still get the desired
result.

PLLOUT = 24 / (0 + 1) * (18 + 1) = 456MHz (within spec)

to remain consistent with the AHB bus. Where the physical size of

the 32-bit boundary are reserved. Writing to these bits has no
