[Why & How]
The aux_rd_interval array in struct dc_lttpr_caps is declared with
MAX_REPEATER_CNT - 1 (7) elements, indexed 0..6. However, the offset
parameter passed to dp_get_eq_aux_rd_interval() can be as large as
MAX_REPEATER_CNT (8) when a sink reports 8 LTTPR repeaters via DPCD.
This leads to an ou... | ```diff

a55a458a8df37a65ffda5cf721d554a8f74f6b04 | Analyze and fix the following issue in the Linux kernel code: drm/amd/display: Fix out-of-bounds read in dp_get_eq_aux_rd_interval() | Problem Details:
[Why & How]
The aux_rd_interval array in struct dc_lttpr_caps is declared with
MAX_REPEATER_CNT - 1 (7) elements, indexed 0..6. However, the offset
parameter passed to dp_get_eq_aux_rd_interval() can be as large as
MAX_REPEATER_CNT (8) when a sink reports 8 LTTPR repeaters via DPCD.
This leads to an ou... | ```diff

nxp_sar_adc_isr_buffer() bails on the first channel-read failure
without calling iio_trigger_notify_done(), so the trigger use_count
is left incremented and iio_trigger_poll_chained() drops subsequent
dispatches until the device is rebound.
