## Summary
drivers/serial/uart_16550: Fix missing semicolon in u16550_dmarxfree()
Commit ceb2921d796 ("drivers: prepare 16550 UART driver to support PCI")
dropped the semicolon after the priv->ops->dmachan() assignment in
u16550_dmarxfree(), so any build with 16550 UART DMA enabled
(CONFIG_16550_UARTx_DMA=y) fails to compile:
drivers/serial/uart_16550.c: In function 'u16550_dmarxfree':
drivers/serial/uart_16550.c:1491: error: expected ',' or ';' before 'if'
Restore the semicolon, matching the TX-side twin in u16550_dmatxavail().
Fixes: ceb2921d796 ("drivers: prepare 16550 UART driver to support PCI")
