[PATCH net 6/8] can: sun4i_can: sun4i_can_interrupt(): fix max irq loop handling

by Marc Kleine-Budde

Reading the interrupt register `SUN4I_REG_INT_ADDR` causes all of its bits to be reset. If we ever reach the condition of handling more than `SUN4I_CAN_MAX_IRQ` IRQs, we will have read the register and reset all its bits but without actually handling the interrupt inside of the loop body. This may, among other issues, cause us to never `netif_wake_queue()` again after a transmission interrupt.

[PATCH] can: rcar_canfd: Fix CAN-FD mode as default

by Biju

From: Biju Das <biju.das.jz(a)bp.renesas.com> The commit 5cff263606a1 ("can: rcar_canfd: Fix controller mode setting") has aligned with the flow mentioned in the hardware manual for all SoCs except R-Car Gen3 and RZ/G2L SoCs. On R-Car Gen4 and RZ/G3E SoCs, due to the wrong logic in the commit[1] sets the default mode to FD-Only mode instead of CAN-FD mode. This patch sets the CAN-FD mode as the default for all SoCs by dropping the rcar_canfd_set_mode() as some SoC requires mode setting in global reset mode, and the rest of the SoCs in channel reset mode and update the rcar_canfd_reset_controller() to take care of these constraints. Moreover, the RZ/G3E and R-Car Gen4 SoCs support 3 modes compared to 2 modes on the R-Car Gen3. Use inverted logic in rcar_canfd_reset_controller() to simplify the code later to support FD-only mode.

[PATCH 1/2] HID: logitech-dj: Remove duplicate error logging

by Hans de Goede

logi_dj_recv_query_paired_devices() and logi_dj_recv_switch_to_dj_mode() both have 2 callers which all log an error if the function fails. Move the error logging to inside these 2 functions to remove the duplicated error logging in the callers. While at it also move the logi_dj_recv_send_report() call error handling in logi_dj_recv_switch_to_dj_mode() to directly after the call. That call only fails if the report cannot be found and in that case it does nothing, so the msleep() is not necessary on failures.

[PATCH] clocksource/drivers/stm: Fix section mismatches

by Johan Hovold

Platform drivers can be probed after their init sections have been discarded (e.g. on probe deferral or manual rebind through sysfs) so the probe function must not live in init. Device managed resource actions similarly cannot be discarded. The "_probe" suffix of the driver structure name prevents modpost from warning about this so replace it to catch any similar future issues.
