Subject: staging: fbtft: Replace magic number with constant
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dbc364054c2e2c7008129237cdaa558656de104d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

staging: fbtft: Replace magic number with constant

Current call to strncmp() uses a magic number. There is a compile
time constant defined for this buffer, included and used already at
other sites in the file.

Remove magic number. Replace with pre-existing compile time constant.
