[PATCH v2] soc: ti: k3-ringacc: Fix access mode for k3_ringacc_ring_pop_tail_io/proxy

From: Siddharth Vadapalli

Date: Fri May 01 2026 - 08:39:30 EST


k3_ringacc_ring_pop_tail_io() and k3_ringacc_ring_pop_tail_proxy()
incorrectly use K3_RINGACC_ACCESS_MODE_POP_HEAD instead of
K3_RINGACC_ACCESS_MODE_POP_TAIL. This will result in ring elements being
popped in the reverse order of that which the caller expects. Fix this.
