[I/J][K/Unstable][OEM-5.14/OEM-5.17][SRU][PATCH 0/1] pl2303: fix type detection for odd device

[Po-Hsu Lin]

[Impact]
After switching to a more strict chip type detection for the pl2303
USB to serial adaptor driver in commit 8a7bf751 ("USB: serial: pl2303:
amend and tighten type detection")

Device with bcdUSB other than 1.10 and 2.00 will stop working. For
example the Cashino PTP-lil/BT24 Slip printer with bcdUSB 1.01.

[Fix]
* e82e7c6dde ("USB: serial: pl2303: fix type detection for odd device")

This patch can be cherry-picked to all of the affected kernels.

[Test]
Test kernels can be found here:
  https://people.canonical.com/~phlin/kernel/lp-1967493-pl2303/

F-5.13 has been tested by the bug reporter and the result is good.

[Where problems could occur]
Change limited to this specific driver (and even to this specific type
of devices), if anything goes wrong the adaptor might be not working.
