2010-06-12bnx2: Fix compiler warning in bnx2_disable_forced_2g5().Michael Chan1-15/+28
drivers/net/bnx2.c: In function 'bnx2_disable_forced_2g5': drivers/net/bnx2.c:1489: warning: 'bmcr' may be used uninitialized in this function We fix it by checking return values from all bnx2_read_phy() and proceeding to do read-modify-write only if the read operation is successful. The related bnx2_enable_forced_2g5() is also fixed the same way. Reported-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2010-06-12enic: cleanup vic_provinfo_alloc()Dan Carpenter1-2/+3
If oui were a null variable then vic_provinfo_alloc() would leak memory. But this function is only called from one place and oui is not null so I removed the check. I also moved the memory allocation down a line so it was easier to spot. (No one ever reads variable declarations). Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: David S.

2010-06-12ethoc: use devres resource managementJonas Bonn1-27/+1
The point of using the devres resource management routines is that they simplify the driver by taking care of releasing resources on failure and release. A recent commit added a bunch of error handling that is unnecessary in this context. This patch removes this redundant error handling, as well as using dmam_alloc_coherent in place of dma_alloc_coherent in order to use this framework consistenly throughout the driver.

2010-06-10gianfar: Revive the driver for eTSEC devices (disable timestamping)Anton Vorontsov1-2/+1
Since commit cc772ab7cdcaa24d1fae332d92a1602788644f7a ("gianfar: Add hardware RX timestamping support"), the driver no longer works on at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more boards as well). That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit: Timestamp incoming packets as padding bytes. PAL field is set to 8 if the PAL field is programmed to less than 8. Must be set to zero if TMR_CTRL[TE]=0. I see that the commit above sets this bit, but it doesn't handle TMR_CTRL. Manfred probably had this bit set by the firmware for his boards. But obviously this isn't true for all boards in the wild. Also, I recall that Freescale BSPs were explicitly disabling the timestamping because of a performance drop. For now, the best way to deal with this is just disable the timestamping, and later we can discuss proper device tree bindings and implement enabling this feature via some property.

2010-06-08wl1251: fix ELP_CTRL register readsGrazvydas Ignotas1-6/+34
Reading the ELP_CTRL register with sdio_readb causes problems because hardware seems to be performing a write using stuff bits in the request (those bits contain write data in write request). This indicates that it actually expects RAW (read after write) type of request, so perform that when reading ELP_CTRL instead. Also cache last written value so we know what to write when doing RAW request. Because of the above it was not possible to wake the chip from ELP power saving mode, PM had to be disabled to have the driver usable in SDIO mode. After this patch PM is functional. For backporting to 2.6.34 or earlier, this patch depends on 6c1f716e8154ee9315534782b9b1eedea0559a24, which adds the required SDIO funcion.

I'm not sure if we need to set the switchtable at the same place in ath5k_hw_reset() as it was before - it is set later thru ath5k_hw_set_antenna_mode() anyways - but i leave it there to avoid problems(?).

2010-06-07r8169: fix random mdio_write failuresTimo Teräs1-0/+5
Some configurations need delay between the "write completed" indication and new write to work reliably. Realtek driver seems to use longer delay when polling the "write complete" bit, so it waits long enough between writes with high probability (but could probably break too). This patch adds a new udelay to make sure we wait unconditionally some time after the write complete indication. This caused a regression with XID 18000000 boards when the board specific phy configuration writing many mdio registers was added in commit 2e955856ff (r8169: phy init for the 8169scd). Some of the configration mdio writes would almost always fail, and depending on failure might leave the PHY in non-working state.

2010-06-06iwlwifi: fix wrapping when handling aggregated batchesDaniel Halperin1-6/+45
Fairly complex code in iwlagn_tx_status_reply_tx handle the status reports for aggregated packet batches sent by the NIC. This code aims to handle the case where the NIC retransmits failed packets from a previous batch; the status information for these packets can sometimes be inserted in the middle of a batch and are actually not in order by sequence number! (I verified this can happen with printk's in the function.) The code in question adaptively identifies the "first" frame of the batch, taking into account that it may not be the one corresponding to the first agg status report, and also handles the case when the set of sent packets wraps the 256-character entry buffer. It generates the agg->bitmap field of sent packets which is later compared to the BlockAck response from the receiver to see which frames of those sent in this batch were ACKed. A small logic error (wrapping by 0xff==255 instead of 0x100==256) was causing the agg->bitmap to be set incorrectly. Fix this wrapping code, and add extensive comments to clarify what is going on.
