Cirrus firmware installation warnings

[Artem S. Tashkinov]

Hi,

I'd like to report an issue with installing Linux firmware:

$ make DESTDIR=/tmp/firmware install
install -d /tmp/firmware/lib/firmware
/copy-firmware.sh  /tmp/firmware/lib/firmware
ln: failed to create symbolic link
'/tmp/firmware/lib/firmware/cirrus/cs35l41-dsp1-spk-prot-103c8ca7.wmfw':
File exists
ln: failed to create symbolic link
'/tmp/firmware/lib/firmware/cirrus/cs35l41-dsp1-spk-cali-103c8ca7.wmfw':
File exists
ln: failed to create symbolic link
'/tmp/firmware/lib/firmware/cirrus/cs35l41-dsp1-spk-prot-103c8ca7.wmfw':
File exists
ln: failed to create symbolic link
'/tmp/firmware/lib/firmware/cirrus/cs35l41-dsp1-spk-cali-103c8ca7.wmfw':
File exists

Not sure if it's worth fixing or not, just pointing out.

Best regards,
Artem
