[PATCH RESEND] bluetooth: btbcm: Fix logic error in forming the board name.

[PATCH RESEND] bluetooth: btbcm: Fix logic error in forming the board name.

[Sasha Finkelstein via B4 Relay]

From: Sasha Finkelstein <fnkl.kernel@gmail.com>

This patch fixes an incorrect loop exit condition in code that replaces
'/' symbols in the board name. There might also be a memory corruption
issue here, but it is unlikely to be a real problem.

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read:
    https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.

Sorry about that, let's just skip the stable tree part for now then.

That's not how to solve the problem, if it's a bug that needs to be
fixed in stable kernels, submit it properly and it will automatically be
propagated there as the documentation states.
