Subject: serial: sh-sci: using correct fifo size for SCIF and SCIFA ports.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=75136d48e85915fd78a072f22897622b5d4c1814;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

serial: sh-sci: using correct fifo size for SCIF and SCIFA ports.

The sh-sci driver used the wrong fifosize for PORT_SCIFA and PORT_SCIF
ports. If an incorrect size is used, the serial core will enforce an
early shutdown on the port, especially with baudrates < 9600.
