If anyone has any objections, please let me know. ------------------ From: Uwe Kleine-König [ Upstream commit 2f3cfd2f4b7cf3026fe6b9b2a5320cc18f4c184e ] For an out-of-memory error there should be no additional output. Adapt dev_err_probe() to not emit the error message when err is -ENOMEM. This simplifies handling errors that might among others be -ENOMEM.
