The ARRAY_SIZE(foo) macro should be preferred over sizeof operator
based computation such as sizeof(foo)/sizeof(foo[0]) for finding
number of elements in an array. Issue identified using coccicheck.

Please please please test-build your patches before sending them out.
To not do so just wastes reviewer resources :(

Hello Greg,
I did build the .ko files by making the driver/staging/fbtft/ path. I verified
.o and .ko files were built.

I did a make clean just now and was again able to rebuild without any errors.
Please see the attached log file.

Is there something wrong with the way I am firing the build?

Thank you,
./drv

thanks,
