Old smatch warnings: drivers/staging/erofs/unzip_vle.c:1322 z_erofs_vle_normalaccess_readpage() warn: should 'page->index << 12' be a 64 bit type? It needs to cast variable's type to erofs_off_t before left shifting. Reported-by:

Logical address of EOF LTP mapping should start at `inode->i_size' rather than `inode->i_size - 1' to `m_la(in)', fix it. Signed-off-by:

This patch separates 'erofs_get_meta_page' into 'erofs_get_meta_page' and 'erofs_get_meta_page_nofail'. The second one ensures that it should not fail under memory pressure and should make best efforts if IO errors occur. It also adds auxiliary variables in order to fulfill 80 character limit.

Pass the gasket driver descriptor to the interrupt init function, rather than exploding out separate parameters from various fields of that structure. This allows us to make more localized changes to the types of interrupts supported (MSIX vs. wire, etc.) without affecting the calling sequence, and seems nicer for simplification purposes.

Split interrupt handler into PCI MSIX-specific and generic functions, for adding non-MSIX handlers in the future. Move MSIX init code together,, out of generic init path. Signed-off-by:

Todd Poynor authored
Some explicit memory barriers in the page table code are not necessary, either because: (a) The barrier follows a non-relaxed MMIO access that already performs a read or write memory barrier. (b) The barrier follows DMA API calls for which the device-visible effects of IOMMU programming are guaranteed to be flushed to the IOMMU prior to the call returning, and doesn't need to sync with normal memory access.

Todd Poynor authored
Use of readl() is deprecated; readl_relaxed() with appropriate memory barriers is preferred. Switch to relaxed reads and writes for better performance as well. Memory barriers required for I/O vs. normal memory access on Apex devices have already been explicitly coded in the page table routines. Signed-off-by:

gasket_alloc_dev can retrieve the device name from the parent parameter, a separate parameter isn't needed for this. Rename the variable to better reflect its meaning, as the name of the parent device for which a gasket device is being allocated. Signed-off-by:

A debug log in gasket_alloc_dev() is issued regardless of whether the device pointer used returned success or error. The log isn't that useful anyway, remove it. Signed-off-by:

This patch removed function named rtw_malloc2d. I removed this function because this function is used exactly once and function call have some overhead also. Maybe this will improve code runtime slightly. Signed-off-by:

Rename the function phy_RF8256_Config_ParaFile() to phy_rf8256_config_para_file(). This change clears the checkpatch issue with CamelCase naming. Additionally as the function is only ever used in one file, (r8190_rtl8256.c), the function prototype has been removed from the header file, (r8190_rtl8256.h). These changes are purely coding style in nature and should have no impact on runtime code execution. Signed-off-by:
