Message-ID: <20141017113123.GA24962@mwanda> (raw)
Hello Thierry Reding,
The patch e687651bc1ed: "drm/tegra: Add hardware cursor support" from
Dec 20, 2013, leads to the following static checker warning:
drivers/gpu/drm/tegra/dc.c:597 tegra_dc_cursor_set2()
warn: mask and shift to zero
drivers/gpu/drm/tegra/dc.c
594 if (bo) {
595 unsigned long addr = (bo->paddr & 0xfffffc00) >> 10;
596 #ifdef CONFIG_ARCH_DMA_ADDR_T_64BIT
597 unsigned long high = (bo->paddr & 0xfffffffc) >> 32;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I'm not sure what the correct mask is.
598 #endif
599
regards,
dan carpenter
