Subject: [PATCH] video: fbdev: atmel_lcdfb: fix return error code in atmel_lcdfb_of_init()
Git-commit: ba236455ee750270f33998df57f982433cea4d8e
Patch-mainline: v5.11-rc1
References: git-fixes
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.
