Subject: [PATCH v1 2/2] serial: 8250_dw: Revert "Move definitions to the shared header"
Date: Tue, 14 May 2024 22:05:54 +0300 [thread overview]
Message-ID: <20240514190730.2787071-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20240514190730.2787071-1-andriy.shevchenko@linux.intel.com>
This reverts commit d9666dfb314e1ffd6eb9c3c4243fe3e094c047a7.
The container of the struct dw8250_port_data is private to the actual
driver. In particular, 8250_lpss and 8250_dw use different data types
that are assigned to the UART port private_data. Hence, it must not
be used outside the specific driver.
Fix the mistake made in the past by moving the respective definitions
to the specific driver.
