Hello there,
[linux-4.1-rc1/drivers/gpu/drm/msm/dsi/dsi_host.c:1799] -> [linux-4.1-rc1/drivers/gpu/drm/msm/dsi/dsi_host.c:1802]: (warning) Variable 'ret' is reassigned a value before the old one has been used. 'break;' missing?
switch (cmd) { case MIPI_DSI_RX_ACKNOWLEDGE_AND_ERROR_REPORT: pr_err("%s: rx ACK_ERR_PACLAGE\n", __func__); ret = 0; case MIPI_DSI_RX_GENERIC_SHORT_READ_RESPONSE_1BYTE: case MIPI_DSI_RX_DCS_SHORT_READ_RESPONSE_1BYTE: ret = dsi_short_read1_resp(buf, msg); break;
Regards
