commit 3cc88e8405b8d55e0ff035e31971aadd6baee2b6 upstream.
The initialization of vport interrupt consists of two functions:
1) idpf_vport_intr_init() where a generic configuration is done
2) idpf_vport_intr_req_irq() where the irq for each q_vector is
requested.
The first function used to create a base name for each interrupt using
"kasprintf()" call. Unfortunately, although that call allocated memory
for a text buffer, that memory was never released.
Fix this by removing creating the interrupt base name in 1).
Instead, always create a full interrupt name in the function 2), because
there is no need to create a base name separately, considering that the
function 2) is never called out of idpf_vport_intr_init() context.
Fixes: d4d558718266 ("idpf: initialize interrupts and enable vport")
