From: Cyril Chemparathy Date: Sun, 2 May 2010 18:28:12 +0000 (-0400) Subject: Davinci: serial - remove unnecessary define X-Git-Tag: firefly_0821_release~9833^2~2113^2~18 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=da0122ca8b7804b9cd8fa7eff466bafba27f09a3;p=firefly-linux-kernel-4.4.55.git Davinci: serial - remove unnecessary define The uart pdata array is already terminated by a zero flag field. This patch reuses this terminator and eliminates DAVINCI_MAX_NR_UARTS definition. This way, future platforms can have different number of uarts initialized via davinci_serial_init().
