Subject: [PATCH 5.7 148/376] ath11k: fix error return code in ath11k_dp_alloc()

From: Wei Yongjun <weiyongjun1@...wei.com>

[ Upstream commit f76f750aeea47fd98b6502eb6d37f84ca33662bf ]

Fix to return negative error code -ENOMEM from the error handling
case instead of 0, as done elsewhere in this function.
