[PATCH v3 3/6] imx-drm: imx-ldb: Fix array length

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>

Fix the following static checker warning:

drivers/staging/imx-drm/imx-ldb.c:340 imx_ldb_get_clk() error: format string overflow. buf_size: 16 length: 18
probably 18 is theory and not real life, but 16 is based on
theory as well.

Changes since v2:
