wifi: ath11k: fix soc_dp_stats debugfs file permission
Currently the soc_dp_stats debugfs file has the following permissions:
# ls -l /sys/kernel/debug/ath11k/pci-0000:03:00.0/soc_dp_stats
-rw------- 1 root root 0 Mar 4 15:04 /sys/kernel/debug/ath11k/pci-0000:03:00.0/soc_dp_stats
However this file does not actually support write operations -- no .write()
method is registered. Therefore use the correct permissions when creating
the file.
After the change:
# ls -l /sys/kernel/debug/ath11k/pci-0000:03:00.0/soc_dp_stats
-r-------- 1 root root 0 Mar 4 15:15 /sys/kernel/debug/ath11k/pci-0000:03:00.0/soc_dp_stats
Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30
