Subject: fbdev: omapfb: lcd_mipid: Fix an error handling path in
mipid_spi_probe()
Git-commit: 79a3908d1ea6c35157a6d907b1a9d8ec06015e7a
Patch-mainline: v6.5-rc1
References: bsc#1154048
If 'mipid_detect()' fails, we must free 'md' to avoid a memory leak.
Fixes: 66d2f99d0bb5 ("omapfb: add support for MIPI-DCS compatible LCDs")
