Fix this Signed-off-by: Bjorn Andersson --- Changes in v2: - Introduced "intents" and fixed a few spelling mistakes in the commit message of patch 1 - Cleaned up log snippet in commit message of patch 2, added battery manager log - Changed the arbitrary 10 second timeout to 5... Ought to be enough for anybody. - Added a small sleep in the send-loop in patch 2, and by that refactored the loop completely. - Link to v1: https://lore.kernel.org/r/20241022-pmic-glink-ecancelled-v1-0-9e26fc74e0a3@oss.qualcomm.com --- Bjorn Andersson (2): rpmsg: glink: Handle rejected intent request better soc: qcom: pmic_glink: Handle GLINK intent allocation rejections drivers/rpmsg/qcom_glink_native.c | 10 +++++++--- drivers/soc/qcom/pmic_glink.c | 25 ++++++++++++++++++++++--- 2 files changed, 29 insertions(+), 6 deletions(-) --- base-commit: 42f7652d3eb527d03665b09edac47f85fb600924 change-id: 20241022-pmic-glink-ecancelled-d899a9ca0358 Best regards,
