From f2edbafc6cb905caec2b231e8e2226b4c75daad9 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Sat, 7 Feb 2026 09:32:55 +0800 Subject: [PATCH] drm: verisilicon: suppress snprintf warning for pixel clock name Although it's generally expected that the pixel clock ID will only have one decimal digit, this isn't enforced in vs_dc.c source code, and the compiler will argue about the buffer being not long enough. Enlarge the snprintf() buffer for generating pixel clock name to be enough for a UINT_MAX pixel clock ID in order to suppress the compiler warning.
