Subject: serial: sprd: adjust TIMEOUT to a big value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e1dc9b08051a2c2e694edf48d1e704f07c7c143c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

serial: sprd: adjust TIMEOUT to a big value

SPRD_TIMEOUT was 256, which is too small to wait until the status
switched to workable in a while loop, so that the earlycon could
not work correctly.
