Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: mhi: fix potential memory leak in ath11k_mhi_register()
mhi_alloc_controller() allocates a memory space for mhi_ctrl. When gets
some error, mhi_ctrl should be freed with mhi_free_controller(). But
when ath11k_mhi_read_addr_from_dt() fails, the function returns without
calling mhi_free_controller(), which will lead to a memory leak.
We can fix it by calling mhi_free_controller() when
ath11k_mhi_read_addr_from_dt() fails.
