Subject: ARM: OMAP: display: change compat names to array
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5b5992ac64a5a609c995807d987459c7759c6fb1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: OMAP: display: change compat names to array

Simplify the DSS detection logic by creating a list of the omapdss
compat strings, instead of checking each separately with an 'if'.
