Subject: serial: pic32_uart: Fix double free of 'sport->irq_fault_name'.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=24a6a3037e0b47168f9b3bb9db7ad60c89dad7ba;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

serial: pic32_uart: Fix double free of 'sport->irq_fault_name'.

Allocated memory for 'sport->irq_fault_name' is freed twice, first
in error check of 'if(!sport->irq_rx_name)' and other in fallback
handler.
