Subject: Bluetooth: 6lowpan: Don't drop packets when run out of credits
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e1008f95e1e7762fade7ccbc973247a3b32edddb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Bluetooth: 6lowpan: Don't drop packets when run out of credits

Since l2cap_chan_send will now queue the packets there is no point in
checking the credits anymore.
