[PATCH 4.19 145/346] video: fbdev: atmel_lcdfb: fix return error code in atmel_lcdfb_of_init()

[Greg Kroah-Hartman]

From: Yang Yingliang <yangyingliang@xxxxxxxxxx>

[ Upstream commit ba236455ee750270f33998df57f982433cea4d8e ]

If devm_kzalloc() failed after the first time, atmel_lcdfb_of_init()
can't return -ENOMEM, fix this by putting the error code in loop.
